solution for the overtrained legs?

Kerry warned me about this. And apparently I forget sometimes that I am 39 (40 this July). I severely overtrained my legs in March in my quest for our team yardage record. He told me that I might not recover for our Pac Champs (I didn't), and I might not even recover for Nats (obviously I didn't). I was ok, not great, for 50s and 100s. But anything over a 100 and I was toast as my legs were just non-functional. I am not complaining/making excuses, for 2 reasons: I achieved my goal and broke our team record, and two, the meet is over and I need to move on. But my question is this: how do you recover o/t legs? I've looked at a lot of sites and haven't seen any good ones, a lot of body building stuff too. I wanted to start running today, but I don't want to dig an even bigger hole than the one I'm in. I've never overtrained anything, so this is new for me. All suggestions are welcome. Stretching- how often? Massage- how often, type? Other?
