Did I overdo it again?

I'm a little concerned because the tightness in my butt seems to be back again. I'm not sure if it's because the steroid treatment is winding down or if I overdid it. I ran/walked yesterday for 5 miles. I felt pretty good so I probably "ran" more than I should have. I never made it to the pool which was probably a mistake. I think swimming is probably very good for it. I'm not so sure about spinning and running. I've never had an injury that has side-lined me like this and have always prided myself in running smart. Boy did I blow that reputation by doing too many long hilly races and not enough recovery followed by too much cross-training. I guess I was just too anxious to get back into it as my running and working out had not been all that great leading up to Umstead due to the initial butt problem. Hopefully a little TLC will coax it along into a full recovery!
