Rode with Todd early in the morning for 1:45. Warmed up for 15 minutes, then rode in the big ring. Pushed up hills fairly effectively, focusing on pulling up and pushing. It went quite well, considering this was my first big ring ride in over a year. So, I'd say I pushed it pretty good. Still felt that vague weakness before I left for the ride, but it didn't seem to affect the riding.
Then, I had a really big get-stuffed-before-Yom Kippur lunch and that seemed to do the trick. Almost as soon as I stopped eating, I felt better and in the ensuing 36 hours I've felt fine. I'm so happy I could release 99 Luftballons. You guess what number ride it was.
