A commute route I often take to get to work

This is a commute route I often take to get to work. I live about 2kms from work, and its all downhill. Good for 14 calories of expenditure according to my power tap. So some times I start by carrying on up my hill until I reach the Danzig MTB track built by the local MTB club. If I ride down it, then back up again, and back down my hill, its a good 60 mins of single-track fun.
