Today was the coldest day I've ever been out cycling. It was 25 degrees when I left; 30 when I got back. Living in (north) Florida, temps don't get too extreme, and I've never decided not to go riding because it was too hot or too cold. After today's ride, my new thought is: If it's below freezing, I'm not riding. My core stayed warm (lots of layers) but even though I was wearing heavy gloves, my hands and feet got really cold, to the point where my fingers were disfunctional. I had to get my wife to unfasten my helmet strap when I got home because my fingers weren't working. I know that people ride in temps like this, but I don't see how. Maybe if I had heated socks and gloves, I could do it. Cold weather riders, any secrets to share?
