Cycling 1:42:00  22.0 mi (4:38 / mi)
Biking to work. I dawdled at home waiting for the temperature to go up, but it didn't, so I left home at 9 a.m. still at 36 deg. F.
I'm going to have to augment the clothing system. I was good down to 39, but those extra 3 degrees were killer. Warmer gloves, socks, and hat to start with, and I think I have to do something to get my legs a little warmer. Seems like an extra layer just over the front of the thighs would do it, but I don't know exactly how to make that happen.
