Coldest ride ever for me this morning: 15 degrees, but little wind. Not too bad. I think I won't ride below 10 degrees. My fingertips were cold and my feet a little too. Wore 3 layers on top and two over my biking shorts along with booties and a balaclava. We're supposed to get some snow tonight and throughout the week so it doesn't look good for my road bike commute.
Bought a cheap Bell headlight to go with my Cat Eye EL400 light that is not quite enough for riding in the dark roads. I road Friday night with it and had to go a little slower than I wanted to. I'll try it out tonight.
