I also picked up some disposable toe heaters, but I didn't try them. My toes were warm enough through most of the ride. The main problem now is that it's hard to stuff three pair of socks into my sneakers, even in my usually too large size 13 Cons. It compresses the toes. Sigh.
My hands weren't terribly cold with just the single pair of riding gloves today, but for the last lap I experimented by pulling on a pair of regular winter gloves over them. It was certainly warmer, but it sacrifices a lot of finger flexibility. Only for really cold days, then.
I was kind of surprised at how little energy I had on the ride until I remembered that I'd spent most of the morning getting a physical and having blood work done. My left arm is very sore both from the blood draw (four frelling tubes) and also thanks to the pneumonia booster my doctor gave me. He promised that I'll never need another booster. Yeah, sure. There's always another.
