Wow, that sucks.

I have a 17 miler and I've done several back-to-backs but have yet to do 3 consecutive days. (I sometimes rode to work 5 days in a week last year when my commute was only 7 miles.)

After a back-to-back though, I tend to just feel fatigued and not really sore. I like to say that I don't get all worked up about other riders, but I have to admit that I pulled out my cell phone to take a picture of some local construction this morning when a roadie zipped by behind me. I hopped on my hybrid and caught up to him and rode with him for a few miles at much more than my normal pace. It turns out we work for the same company, although different locations, and have some common friends. I was relieved when he turned left and I turned right.... I could go back to being a pokey butt.
