Why? Because it's -5 degrees C outside and I'm going nordic skiing in an hours time. We'll probably do ~ 15 km at Sovereign Lake (one of the top Nordic centers in North America, site of FIS World Cup Races in Dec.) then back home about mid-afternoon and I'll try to get in an hour/hour and half on the bike if it warms up above freezing.

Why are you still on Bikeforms?
