Went riding with Roger in the afternoon. The weather was cold. I wore full gear, but it wasn't necessary. I wore my wind breaker and took it off for the trip back. I was about to decide not to go for a ride but decided to go at the last minute. I felt ok until the return trip. Almost immediate after the turn around, when I removed my jacket, I felt qweezie, almost nautious. I felt this way most of the way up the mountain. I feel ok now (a few hours later). My bike didn't make any clicking noises when going out of the saddle. I tightened the stem on the previous ride. I think that did the trick. My body was responding well, we kept a nice solid tempo. It felt like a vigorous workout which is what I needed. When I was going down Woodford-Teh road on the downhill I could feel my right upper calf just barely cramping. I was able to prevent it from getting worse by slightly reducing my effort.
