...Anyone got tips for staying warm on the bike? My riding partner had to pack it in after about 10 miles today with temps in the high 30s. She was dressed in the usual layers (maybe not enough) with a windbreaker shell and even tried those old-timey chemical hand/feet warmers. We were riding on gravel roads with MTBs to keep the wind chill down. I would have kept going, but I was a little chilly myself. Feet and hands were the deciding factors.
