Thanks guys for the ideas and well wishes. I have a good GI that I work pretty closely with. He already has an email from me. After the 159 mile ride, I took the whole week off the bike except for 1 recovery ride. Then I proceeded to ride RAGBRAI the following week, which was about 550 miles over 7 days. After that, I took a couple days off then cut back on my riding a bit. I use bike journal and I'm averaging about 2 rides a week now. I've stopped riding with my club altogether because there's no way I'd keep up and it'd just wear me down psychologically.

I know I need to get over the need to go fast, but you're right. It is hard once you can. I get so much enjoyment out of riding that to let this sap that out of me is stupid. But right now I'm just angry and want to know why

I'll let you know if my doc figures anything out. In the interim I'll do my best to stay in the saddle.
