A few years ago, there were some PT folks on this site, so I am looking for some advice. I am trying to run my first half marathon in 2 weeks. All runs have been great recently, knocking out 10 miles without an issue. On Saturday morning, I upped the run to 11 miles, which added significant hills. By the end of the run, I could feel things getting tight, extending from my rear, down my leg and across my knee. This was in both legs. I believe that I have angered the IT bands in both legs. I am rolling and stretching, but things are very sore. Any recommendations on what I should do up until my run? Should I stop running until then?
