Boganduro


Update 1. Weather is looking good !
The Welly contingent will go for a beer to the Sprig and Fern on Tinakori road after the ride.

If you have any questions then email me using the contact form.

Cheers, Jeff

Details below...




The Boganduro is a casual gravel grinder in the Grinduro format with self-timing based on the STRAVA app installed on your phone.

It will be on gravel where possible, with around 1600 metres of climbing. The Boganduro starts in Wellington, or the Hutt Valley, and takes in Battle Hill and Belmont Regional Parks.

This is a chance to catch up with your buddies and have a good old chin-wag, and if you are up for it, lay down the hurt on a couple of climbs or downhills, if that's your thing.

Don't forget to dress sensibly, it could get cold, bring food and water, tubes and tools. Have the course at least on your phone or GPS. ( you may like to download the GPX file below ). Familiarise yourself with the course in the event that you get lost. Course notes  below. Please read them at least once.

Starting point:
Wellington Train station. 8am and
Petone Wharf 8:40am, Saturday November 23rd.

Cost: Free
Food availability: Pauatahanui Cafe / Dairy enroute.
Bail-out points: Judgeford, return to Hutt Valley via Haywards on the road.

It's fully self supported, bring tools and a couple of spare tubes and kit.

Be prepared for all weather and to ride for up to 96 kms max, but around 74kms if you are only starting in the Hutt.

Use #boganduro to share  related bumpf in your social media if that takes your fancy.

To give you an idea of the terrain, here are the STRAVA timed segments that will most likely be on the course. My suggestion is that you will want at least 35mm tires.

The full ride on Strava can be seen here:https://www.strava.com/activities/1255586562

The Strava timed segments are shown here.

I have done a couple of reccies on the 3 of the 4 sectors of the #Boganduro. The downhill segments are both mint, and the climbs are... climby : ) the major climb (Puketiro/Cooks Road) you should be able to do in a 1 to 1 gear, so a 32/32 or similar, but YMMV. Strava tells me that there is at least 1 km at 20% on this first sector, but overall it is 8%.

K-Lite 2nd impressions

I was very excited to get a hold of the latest kit from K-Lite to run through its paces recently. Kerry is constantly iterating his designs but recently he has launched a couple of very cool additions to his line-up. His new rear flashing lights, (QUBE) and a new USB converter with dual outputs.

If you followed the world's gnarliest bikepacking events, like the Tour Divide, or the Silk Road Mountain Race you would have noticed that many of the riders were using various models of K-Lite kit. These guys are using the kit in the crucible of fire, if anything can possibly go wrong, it will.

Dual-port USB-charger, QUBE flashers, switch wire/loom and front light.

The flashers
Kerry makes the only dynamo powered flashers, in the world, called the QUBE, available in 1x or 2x formats, or front and rear sets, for attaching to the seatpost, seat stays or bars.

Runs for 3 mins after a 15 second spin of wheel.
Somehow he has crammed little super capacitors into them so that a 15 second spin of the front dynamo wheel means your rear flashers will go for 3 mins before needing more juice. Not many traffic lights take that long to change. 

The QUBE flashing pattern seems quite random, but in fact, the LONG/SHORT flash-pattern is actually what NASA use. It is the best for judging the distance to the rider, and also catching the eye from a distance.

They are very bright and yet Kerry tells me they draw less than 30mA intermittently, a typical rear dynamo light draws 110mA at all times. That's a big difference. If it means anything to you, the standard bikepacker's GPS, the Etrex 30, draws 50mA-110mA (back light dependent) at 5 volts. 


Even in the daytime the QUBE's are a great addition.
Kerry has also done something smart with the optics, so that the further you are away, the brighter they look, the idea is that the rider behind, sitting on your wheel, is not blinded, but a car, in the distance gets full blast, clever stuff. These QUBEs are the only item that Kerry is building by hand these days, so he only does a run on them when he has a big enough order. Check your local K-Lite dealer for stocks.


The switch / wire loom
Mount the switch on bars, stem, or steerer
The switch wire/loom comes in two styles. The first one is where the USB-charging out-puts are active all of the time, and you just toggle the front light off and on. This is the mode you will need if you are wanting to run the QUBE flashers.

In the second style, you just flip back and forth between front lighting, or USB charging.






The USB charger

Kerry has some clever smarts hidden in the new dual-port  USB-charger to help with charging supercap systems like the QUBE. He has more smoothing caps than any of the other USB chargers out there. This does make it a little larger, but it allows safe direct connection of phone or GPS to USB charger, should your USB cache battery stuff up.

Normally connecting a sensitive USB device direct to a dynamo charger (without an inline cache battery) is not advised, as the output can be a bit "choppy" due to the AC conversion done on board. This can cause re-sets and crashes of sensitive USB devices. In the new K-Lite charger with its extra smoothing, it offers another layer of back up, in an emergency situation.


The new design retains the little LED activity light introduced in the previous model, so you know if the power is making its way from the dynamo to the charger. Apparently the new USB charger lets you run your SPOT-tracker and charge your USB cache battery at the same time, because the SPOT trackers draw so little power.

The SPOT-tracker will run from the dynamo all day and automatically switch to it's own battery only when you have stopped moving. You can even power your SPOT tracker with no batteries in the bay, just plug it in to the USB-charger and get pedaling. I haven't tried this out myself as I don't have a personal SPOT tracker. As in his previous model Kerry has all the plugs going in and out of the USB-charger at the same place, this is great for space saving in your gas-tank, if that's where you store your electrics.

Here are a few potential scenarios that you might hope to run from your dual USB-charger. Obviously it depends on whether its day or night, and the terrain, as the front lights will use a lot of the power coming from the dynamo hub at night time.

Night-time riding
  • Front lights and QUBE F and R flashers
  • Front lights and QUBE F and R flashers and GPS (Etrex and Edge as they are low powered)
  • Front lights and QUBE rear flashers and GPS and SPOT tracker. In this scenario you'd need a USB splitter as there are only two out-puts from the USB converter. It's not until the demand exceeds 500mA that you start to rob power from the front lights. Flashers+SPOT+GPS should be under 500mA if you are moving at any kind of pace.

Day-Time riding
  • Charge cache and run SPOT tracker
  • Charge cache and run QUBE F and R flashers
  • SPOT tracker and GPS 
  • SPOT tracker and QUBE rear flashers 
  • SPOT tracker and QUBE rear flashers and GPS (need a USB splitter).

Obviously the idea is to charge your cache battery in daytime if you can as there is a lot more power available when the front lights are off.

My experience with the USB charger and the Etrex GPS was pretty good. Basically, if you have it plugged in to the USB-converter, and you are moving, it defaults to the dynamo for power. I found that it wasn't until I dropped below 9 kmh that I got the nag-screen. However, if you run the GPS via a cache battery you don't get the drop-out at all. Etrex AA batteries last for 4 days anyway, and are easily available at most stores or gas-stations, which is why they are so popular.


My buddy ran his Garmin 1030 without a cache battery in the Japanese Odyssey last year with no problems using his K-Lite kit. It would just drop down to the internal battery when the dynamo power was too low. The 1030 is a much more sophisticated piece of equipment than the old Etrex though and you have to look at the pros and cons of each device. Matt pointed out that in Japan a lot of the riders used phones instead of GPSes for navigation. In an event where most of the people are topping up their devices in accommodation over-night it's an option.


The lights
The lights have undergone a weight-loss programme that shaves a bit more meat off them but they still share the same internals as the previous model. Coming in 2 variants, the Gravel/Road and the MTB, the major difference being that the MTB has a wider more diffuse spread for the great outdoors, vs the more punchy beam of the Gravel/Road light which has to compete with urban light pollution.

In both variants the outside lights come on first and are supplemented by the centre beam at higher speeds. Everytime I go out I am amazed at the strength of these lights.

The new K-Lite kit also contains an adaptor for the Universal fork crown mount, allowing easy connection to Supernova or B&M style mounts. The GoPro mount is still a very popular mounting mechanism, and rightly so, with thousands of cheapie variations of it available online.





I did a bit more field testing in the weekend with a proposed trip down south to do the Old Ghost road. There was always the chance that the weather was going to be bad, so I had to be open to other options, and I had plans to visit my parents 120kms away in Nelson. As it happened, the trip was cancelled and after some local riding, I rode over the Mangatapu Saddle that links Nelson to Marlborough. I had installed the Dynamo Kit on my Santa Cruz Tallboy mainly for safety as I knew I would be on the seal for at least 60 kms. The dazzling brightness of the rear QUBES made me feel a lot safer on a main road with no shoulder, on a Sunday afternoon. What really impressed my though was the low speed at which the QUBES kicked in. I confess I haven’t checked it with a computer, but for most of the 14.3% hike-a-bike section on the Mangatapu saddle the little buggers were flashing away maniacally. That was an average speed of around 3.3 km/h. Impressive.



Kerry is always tweaking and launching new stuff, so if you want to get the heads-up on his next thing, its best to follow him on http://instagram.com/klite_dynamo_power/  He has quite a few things going on in the back-ground just now.

If you want to get a feel of what is behind the K-Lite ethos then tune in to this podcast,  https://bikesordeath.com/ep-22-kerry-slaite-mad-scientist-klite/ I guarantee you will be entertained. Warning, contains occasional expletives.

A hidden epidemic

I walked out of the office the other day and saw one of my workmates chilling in the hallway. She was wearing a peaked hat and dark sunnies, and yet it was overcast and raining outside. She'd just stepped out of a crowded meeting room for a break, she was overstimulated and needed to get out for a few minutes to relax.

I hadn't seen her for quite a while, but I knew the reason behind her absence as I'd heard the rumours. She'd had what is often called a "concussion" or a TBI (traumatic brain injury) depending on how you want to call it. Her fatigue levels had reduced down to the degree that she was able to do some work, but exposure to artificial light, and even computer screens had her feeling nauseous, hence the hat and sunnies.

We had a chat and she talked about her progress and the advice she'd been given by another woman scientist at my work who is still recovering from a head injury she received one and a half years ago. The advice was to take the time to come right slowly, don't try to come back too work to soon.

These are highly achieving people who typically find this kind of advice hard to take. Another buddy of mine, also a woman scientist, but not at my work, was also badly concussed recently in a cycling accident, but her recovery has been pretty swift, by comparison to the first two. The first weeks were pretty bad, and being the co-leader of a 12 million dollar project, she's not the kind of person who thinks its acceptable to take a nap half-way through the day.

If I do a tally up, I can think of 4 people I know of at my work, or who work with the scientists at my work who have received head injuries in the last 2 years. All of them very highly intelligent professionals. None of them risk-takers, all of them with access to good medical advice and an understanding work-place.

What if you didn't have access to all the support systems that a well paid professional with a PhD has? What if you were young and bullet-proof and a risk taker by nature? What are the chances that somewhere along the way you are going to get a good smack on the head, give someone else one, or get head-injured in a car accident? What percentage of people in jail have undiagnosed head injuries? Do you know what some of the side-effects of a head injury are?

Disinhibition, low tolerance to stress, depression, emotional lability, difficulty concentrating, sensitivity to noise or light, aggression, impulsivity, irritability, confusion, sleep disturbance, visual problems, memory problems to name a few.

If you were in the wrong place at the wrong time, with poor support, these behaviours could easily see you in trouble with the law, especially if you medicate with drugs and alcohol.

I've also met a few cyclists on social media who are recovering from head injuries, and sadly as time goes on, I watch new people join them. Hitting someone's wayward dog at 50kmh has that kind of an effect.

So what can you do, not go outside? It wouldn't have helped the two women at my work, one banged her head on a cupboard and the other slipped in the shower. Just look after yourself, the best way you know how. And if you come across someone who has a head injury, try to understand what might be going on on the inside.

Factoids:
  • NZ's ACC's statistics show that in 2015 most brain injuries happened at home (5674) or on the sporting field (5394).
  • The major causes of brain injury are car crashes, sports injuries, assaults and falls.
  • Shockingly, the highest risk groups of New Zealanders for traumatic brain injuries are not our rugby players or our boxers - it's our toddlers

Wildgripper homage saddle

With the single-speed nationals coming up I needed to get a bike ready. I didn't have a lot of choice in the end and it came down to repurposing my 1993 Litespeed Ocoee. The Compass Rat Trap Pass tires had to go, and I figured the drops could go too. The obvious tires to use were the Simworks Homage's which were currently on my 26 inch Santa Cruz Superlight.

Once the tires were mounted it seemed fitting to me that I needed a matching saddle, and I had a dead Michelin Wildgripper that was screaming out to be repurposed.

I cut one up and glued it onto a spare carbon weener saddle that had been doing nothing. I thought it looked alright. The carbon base was very very stiff tho....

Michelin Wildgripper Homage version 1. Carbon base.

A couple of days later I decided I better do my first single-speed ride since the nationals in 2013 and I went out for a 3 hour ride with Mossieur Veganburger. I didn't use the Green saddle, but used a yellow Tioga Spyder knock-off. It was very very comfy.  What if I could combine the comfort of the Spyder with the looks of the Wildgripper Homage?

There is a lot less surface area in one of these saddles, so I would have to sew the pieces together first, with mint flavoured dental-floss, then glue it on.

It worked better than I thought. I'm not going to put Busymanbicycles out of a job anytime soon, but it was a lot of fun.

Michelin Wildgripper Homage version 2. Plastic base.

Fingers crossed it hangs together for the nationals in Te Mata peak this weekend !

Le Petit Brevet - where too much climbing is a thing

Le Petit Brevet is one of those rides that both entices and scares at the same time. I'm not getting any younger so when Scott Emmens announced he was going to organise it this year after a 3 year gap since the last one, I thought I better hop on board. The thing that you struggle with from looking at the stats, is how you can get so many vertical metres into that many kilometres. Well, all I can say is, you do.  There are only about 50 kilometres of flat in the whole ride. Typical Dirt Brevet type rules apply and you have to finish inside 36 hours.

24,888 freedom feet of climbing. If you don't enjoy climbing, it's probably not for you.

I was lucky to have my buddy Ian and his family host me, and quite close to the course, in Mt Pleasant. After unpacking my bike I noticed I could no longer get big/big in my gears and my rear disc was rubbing. Something must have shifted in the travel process.  I decided to adjust the limit screw and reset the rear caliper. I tootled off up the hill to make sure everything was meshing, it was. Up ahead I saw a couple of MTBers so I caught up to them to say hello. The older of the two checked out my bike and asked if I was doing the LPB, as his workmate was organising it. When I asked what his name was, and he said "Guy". The penny dropped. I don't think we'd met since the 2010 Kiwi Brevet when our crew came across Groundeffect's Guy Wyn-Williams and Laurence Mote heading into Darfield, or thereabouts. They had the "local knowledge" so we were happy to get on board with their suggestion of a pretty comfy spot sleeping on the porch at the Oxford Pony Club Domain. The funny part was when they got a small head start on us in the morning and we watched them cycle down the road and take a wrong turn in front of us! I don't think we saw them again. Small world anyway!

22 nervous riders, wondering what they just signed up for.
I digress. The next morning Ian and Lucy kindly dropped me off at Hansen Park where around 22 riders nervously waited for the start. Someone named "Tad" hadn't turned up, but he was on the list, so we waited a bit longer and eventually left without him. There was the usual array of completely different bikes, all of which would be perfect for the job at one stage or another during the ride. I was seriously doubtful of the kit that some people were carrying. They either had their mum waiting ahead fluffing the cushions for them in Akaroa, or they were planning on having balmy weather for the whole ride. As usual I was packing my fears, with a puffer jacket, buff, beanie, rain pants  bivvy sack and quite a few other things I considered bare essentials in case I had to sleep on the roadside.

The initial pace was a bit hot I have to say, and eventually I found out it was crusty Andy the Badger Beale who was the culprit. I struggled a bit on my rigid drop barred bike as we entered Kennedy's Bush, but the single track there was the only single-track I did at pace anyway.  I ended up riding with fellow Wellingtonian Dr Nick Kennedy. Nick is pretty fit so I asked him lots of leading questions about his medical specialty to make it harder for him to pedal and talk at the same time. Nick countered by asking me at what point old people noticed a measurable decline in their performance - he was about to find out. Nick had spent a bit of time in Christchurch so he had a bit of local knowledge and was nailing the sealed descents we rode early on. We stopped at the first cafe we saw and Nick quickly downed a pie and a coffee. I hadn't developed a desire to eat at this point so I stowed a couple of pies in my back pack.

Nick Kennedy. On a sensible bike. Cannondale hard Tail.
We carried on at a pretty good pace and got through a fair bit of climbing. The climbing was pretty constant. There were two main types of climbs. Steep, and bloody steep. After a while I pretty much stopped even using my big ring, just to save the hassle of changing gears. My little gear of 24 on the front was not that much smaller than the big gear of some of the 1x set-ups out there anyway.

Eventually we got back onto some gravel, some really steep gravel, I suspect it was Pettigrews road. We had been riding very solidly for about 70 kms at this point. I was using my new Compass Antelope Hill 2 inch slicks, and even on this crazy steep stuff there were no problems with traction. We did see Andy Beale up ahead, pushing his bike up the road. Probably a victim of his early pace and his big front ring. After about 5 minutes it turned out that riding was marginally quicker than walking, and we caught him. He was in good spirits and was fun to ride and walk with for a bit. He was on a hard-tail like Nick so as soon as we hit the off-road leading into the Double Fenceline track I told them to go on,  as I seemed to be in energy deficit and I needed to get one of those pies circulating through my system.

Taking a breather before the Double Fenceline Track.
My first pie still had little attraction for me but I forced most of it down and left the rest for the birds. It was good to take my first "breather" in about 4 hours, and after that I concentrated on taking a few photos. There was a small problem. The higher I got, the better the views were expected to be, but the tops were often enclosed in cloud. On the other hand, if it had been full sun the whole time it would have been even more brutal.

Stiles were the reason I didn't put all my gear in a frame-bag.
The Double Fenceline track wasn't particularly enjoyable for me, and my bike seemed to be getting heavier with each stile. I was surprised to see people out riding this trail for fun. The going was very slow, but after a very long time (2.5 hours) I was temporarily down on the flat again making a 2km return diversion to the Little River gas station to stock up on fresh Pies and Lolly-water. On the return I had my head down and after climbing 2 kms up SH75 I realised I had missed the turn off to Puaha Road. DOH !

Another pie stop after a foolish distraction on the smooth tarseal. What was I thinking? I need more kms?
I stopped a little way down Puaha road for a break and to get some food in before the next major ascent started. A lot of the climbs so far seemed to be around 6 to 11 %, and I think there was only one of the 10 major ones that was under 400 metres (1400 feet). Little Akaloa was beautiful, with amazing views all the way around to Okains bay.

Heading up along towards the Double Fenceline track. I think.... Looking out over Duvachelle Bay.

As I was just about to get stuck into "Big Hill" coming out of Okains bay, I met up with another rider, Andrew Laurie. Of course, I didn't know it was Big Hill, and Andrew was surprised to see me, not knowing that he had passed me when I'd taken my 4km diversion up SH75. Andrew and I enjoyed riding together for a good while, but his head was a lot stronger than mine and I had to drop off the back when I ran out of concrete pills on a particular climb. Andrew seemed to know quite a few of the climbs which was helpful.


I knew I was getting close to Akaroa, but I couldn't believe how long this 65 kms from Little River was taking. I'd left Little river at 2pm, so it looked like it was going to take me at least 6 hours to get to Akaroa. In my head I had broken the distance to Akaroa up into 2 segments, the start to Little River, about 100 kms, and Little River to Akaroa, another 65 odd. I was hanging out for the smooth tarmac descent down into Akaroa when I checked my GPS to see that I was hanging a left instead....

I got seriously flummoxed at this point. I was making hard work of the directions on the cue sheet, and how they related to where I was going. I back tracked a few metres and eventually worked out that I shouldn't have crossed the style. I had just jumped onto the correct trail when I was surprised by a rider coming up behind me. It turns out he had missed the start by an hour, starting at 8am. He wasn't carrying much gear, in fact, he wasn't even using gears. It was Tad. Some how I put two and two together and worked out that he was the guy we were waiting for at the start, and he was the World Singlespeed champion! Cripes, riding that course on a single speed sounded like the definition of insanity. He admitted to doing a bit of walking. He was on a very cool purple rigid Surly Karate Monkey. I was trying to pick his accent thinking that maybe he was Irish, but it transpired that he was originally Czech but has been in NZ for some years. There must be something about Czechs as there was another on the ride, Martin, currently living in Nelson. At the beginning of the ride we laughed about how difficult it was for Martin to get a visa while a Czech drug dealer currently in jail had no problem getting his okayed!

Gorillas in the mist
The Purple Peak Stock Track trail down into Akaroa wasn't exactly flowy and I was starting to despair of getting into town before the shops closed. I got in at just after 8pm I think and was lucky to find a fish and chip shop that while it was officially closed, took pity on me and took my 37$ for a scoop of chips and fish,  2x Powerade, 2x juice and a couple of water bottles.

Andrew Laurie. Great company.
I was so intent on getting food that I hadn't really thought much about the option of staying the night in Akaroa. It made a lot of sense, but I hadn't booked anything, and I had come with the intention of riding through, even though I knew that I was very under trained for that kind of an effort. I figured that if I wanted to I could have got accommodation, or if I blew up spectacularly in the last leg I could jump in my bivvy sack in a hedge somewhere.

The last "leg" was around 100 kms and I would be doing it in the dark. From memory it had 2 large hills in it. I figured that if I took enough food and rested up if I needed to, I could get through, and there was the promise of... joy of joy, some flat riding before the hills. So I turned on my head-light and rolled out of Akaroa at about 9pm and bang, straight into some more hills....  I saw a sign on the side of the road that said "Camping Ground"... I weakened for a moment..... no turning back now.

I lapped up the flat stuff when I eventually got to it (after the first major hill) and I'm pretty sure I even had a tail wind. Before long I was climbing again and seeing up close what a massive problem we have with Possums. I must have seen at least 50 on the trails. The problem with riding in the dark is that there is not much to see. I was starting to get bored and it was messing with my motivation. There was still a lot of climbing happening. Funnily, for someone who loves climbing, I had for the first time in my life discovered there was such a thing as too much climbing. I remembered my phone, I was Stravaing the ride so I had brought two sets of 2x18650 DIY power-banks for it. For the first time ever I was using the phone in airplane mode and was amazed at how little battery it was using. I turned on my Podcast app, if I jammed the phone in the top pocket of my pack's strap I could hear it loud and clear, and it was less intrusive than headhones. For the rest of the ride I treated myself to stories on such diverse subjects as Lab-grown meat, Fake illegally imported aphrodisiacs, to a critique of Madonna's album "Like a Prayer".

Christchurch looms.
It was getting cold so I started wearing my buff, and even put my emergency shower cap on, as well as my rain jacket, for the cold descents. The lights of Christchurch came into view, and then the day started to break. I've only even ridden into the morning once before, and it is quite a buzz. The only problem I had with navigation the whole time was getting back to Ian's house at the end, using Google maps. Scotts LPB GPX file was perfect. So good in fact, that most of the time I am ashamed to admit that I just followed the line and didn't need to use the cue sheets at all.

I had no idea who else had ridden through the night like I had, only 3 other nutters as it transpired, and unlike me, they hadn't mucked around.

First in was Josh Aldridge in a mind blowing time of 14 hours and 56 minutes, he had finished by 10 pm ! That is insane. Next was another Nelsonian, the Czech Martin Strelka finishing at 11:40 pm. His ride was very impressive, on a very nice looking Salsa Cut-throat. Then there was Andy Beale at 1:44 am. I'm not sure what I was doing in the 3 hours between Andy and my time, I guess just riding very slowly ! The other 15 riders that followed the exact course finished the next day.

Plastic fantastic with bald tires, Compass Antelope Hills.


I've done a few interesting one-day rides over the years, but none as hard as this one. If you love the hills, are up for a challenge and want to take in some amazing views, then Le Petit Brevet just might be for you. Scott did a great job organising this for us, thanks again Scott!

Compass Antelope Hill - short review - long ride

I have been using the Compass Antelope Hill tires for a few months now and gave them a seriously good testing a couple of weekends ago in Le Petit Brevet. There will be a post about that soon. Nominally 55 mm, but actually 53 mm wide on my rims. They are very similar to the Compass Rat Trap Pass tires I have been using for a couple of years, the main difference being that they obviously don't spin up as quickly as the smaller 26 inch variant.

They roll pretty well, similar to a Stans Raven, maybe a tad faster given their lack of any real tread. Le Petit Brevet was a pretty good test for these tires. A reasonable amount of seal, a lot of gravel, a good amount of grass. Lots of uphill, lots of down and a smattering of flat. I did 289 kms with 7900 metres climbing with no issues at all. I was very luck to get dry weather for the whole ride and only once experienced one skid while descending on some damp grass in the evening.  They coped with the gravel descents and the gravel climbs really well. On the steepest climb I could hear the knobbly tires of one of my riding buddies slipping, while the Antelope was still riding smooth. I upped my front rotor from a 160mm to a 180mm for this ride as well so there was some "spirited braking" going on.

I rode with 30 psi (with tubes) in both ends. I could have gone with a bit less but was happy to have a bit more air when I came to a complete halt after banging into a rock on one occasion.

These tires are pretty expensive by the time they get to NZ, but then a lot of tires are. If they wear as well as my Rat Trap Passes have I will be pretty happy. They have a good thick centre area. The only punctures I have ever had on my RTPs were caused by thin pieces of wire.

Reported weight is 535 grams for the standard weight and 465 grams for the light-weight.

Update 3:
Don't forget to dress sensibly, it could get cold, bring food and water, tubes and tools. Have the course at least on your phone or GPS. ( << you may like to download the new file, I think the other was faulty). Familiarise yourself with the course in the event that you get lost. Course notes here. Please read them at least once.

Update 2: 
The Belmont Regional Park will no longer be closed for lambing as of the 20th October, this weekend, if you are one of those unscrupulous sly trainers looking for course knowledge ; )  The timed segments below are at this point a rough guide. They may be tweaked one way or another. YMMV.

Update 1: 
The Boganduro is a casual gravel grinder in the Grinduro format with self-timing based on the STRAVA app installed on your phone.


This is a chance to catch up with your buddies and have a good old chin-wag, and if you are up for it, lay down the hurt on a couple of climbs or downhills, if that's your thing.

It will be on gravel where possible, with around 1600 metres of climbing. The Boganduro starts in Wellington, or the Hutt Valley, and takes in Battle Hill and Belmont Regional Parks.


Starting point:
Wellington Train station. 8am and
Petone Wharf 8:40am, Sunday October 28th.

Cost: Free
Food availability: Pauatahanui Cafe / Dairy enroute.
Bail-out points: Judgeford, return to Hutt Valley via Haywards on the road.

It's fully self supported, bring tools and a couple of spare tubes and kit.

Be prepared for all weather and to ride for up to 96 kms max, but around 74kms if you are only starting in the Hutt.

Use #boganduro to share  related bumpf in your social media if that takes your fancy.

To give you an idea of the terrain, here are the STRAVA timed segments that will most likely be on the course. My suggestion is that you will want at least 35mm tires.

The full ride on Strava can be seen here:https://www.strava.com/activities/1255586562

The Strava timed segments are shown here.

I have done a couple of reccies on the 3 of the 4 sectors of the #Boganduro. The downhill segments are both mint, and the climbs are... climby : ) the major climb (Puketiro/Cooks Road) you should be able to do in a 1 to 1 gear, so a 32/32 or similar, but YMMV. Strava tells me that there is at least 1 km at 20% on this first sector, but overall it is 8%.


96 kms from Wellington to Wellington

* WARNING. Dropbox have deliberately made the download procedure confusing so that people THINK that they need to join up and login to dropbox. You do NOT need to.

When the big white login button appears, click the small grey X in the top right, and continue on, repeating what you have already done.

Once the file is saved you can Drag n drop the file onto your GPS or smart phone. I don't know what you do if you have an Iphone but I heard recently that Apple were going to invent "drag n dropping" of files. Fingers crossed!

There are plenty of phone apps that allow you to view a GPS file. The one I use is called New Zealand Maps.

There is another map here which gives you a good idea of the course, but it is temporary.

Youtube of the Bull Run track here. This is the only technical part of the course. Slow down if you are not a confident rider. There are only a couple of small drops in the course.  Another version of it here with better lighting.

Looking at your segments
After you have finished your ride you can upload the file using Strava. Go to the Boganduro segments under your results, look under the "LEADERBOARDS" for "Todays" results.






































Results from last years Boganduro are here.
