I think one of my biggest mistakes after getting doored in 05 was not pushing myself hard enough to get myself back in shape. I'd been working hard for a few years to get fit and while I was back on the bike pretty quickly (about 3 weeks) I was pretty timid and pretty much stopped doing any other conditioning or weight training. It's taken me a lot longer to get back to where I was because of this. That being said temperance is key, and listening to your body is also key. Maybe try going on that ride but take it easy and see how it feels today? Take a break and stretch out a bit?
