It sn-rained here yesterday. Nice, fat, wet, heavy flakes that were mor congealed droplets of water rather than flakes. My toes were cold, needed better socks, and I wished I had gone with my full rain pants rather then running pants. I've added a couple of spare layers to my bag and broke out the wool socks.

Someone posted the formula to calculate the degree to which the change is temperature and air density effect your output levels on the bike commuter part of ******.

I love riding this time of year. To me the worst part of riding fixed gear in the cold is how much the chain stiffens up, other than that, layers make it all easy.
