I went to a PT for IT band issues last year and don't really feel like they helped me. By the time I got an appointment with an orthopedist to diagnose the issue and give me a referral to the PT, and by the time I got my first PT appointment, the problem had started going away on its own. The woman wasn't particularly knowledgeable about running, and she made me do the same exercises everyone else with "knee" problems had to do. That experience has tainted my views on PT a bit! I will most likely be going to the doc when I return from FL. I am not 100% against going, I just didn't see the point in going 10 days from my trip when there was little they could do.
I plan to walk all of the races with little jogging spurts here and there to keep my pace low enough. If the pain gets to a point where I have to limp, I will stop. Unless that happens during the marathon, in which case I will limp as far as I can go
