Over the past few weeks I've been upping my mileage, from my usual 30-32 to 40-42. I rode 42 last Sunday and 40 yesterday. Last Sunday, I felt like a million bucks and yesterday I felt like...well, like you-know-what. All around. My muscles and joints hurt, my breathing was the pits, and I struggled up every little roller. Jeez, if that had been my first ride ever, I'd never have gotten on a bike again. I can't think of anything I did differently other than spending too much time at my desk during the week and having pancakes for breakfast rather than my usual oatmeal. It doesn't seem like that should've been enough to change the whole ride experience like it did.

Have any of you had this kind of experience, where you feel great one week, then do virtually the same ride the next week and feel like you can't wait to get off the bike?
