Not sure what you mean by "today I tried to go out and nail up a quick 10mi." but it sound like you didn't take it easy. Did you not ride yesterday (Sunday)?
I hardly ever take a day off completely (no riding), but for one or two days after a hard ride, I ride very easy miles -- never letting the HR get above recovery rate. But I think it is advantageous to get back on the bike and get blood flowing through those muscles and loosen them up.
