Since I ran the Cleveland Half-Marathon, I've been dealing with ITBS in my right knee. ITBS is Illotibal band syndrome, an inflammation of the tendon that runs along the outside of your knee up to your hip. Ironically, I developed ITBS in the exact same knee in the fall of 2010 after running the Towpath Half Marathon. Apparently, half-marathons give me ITBS.
It has not curtailed my running, but it has reduced it. Faster running seems to aggravate; sticking to around the 9 minute per mile pace seems to keep it under control.
I haven't really found anything that helps. I tried a foam roller, and it may have marginally helped. I've tried the various ITBS stretches, but they don't seem to do much either. I wear an ITB strap pretty much all the time, and that seems to help some, although it isn't a cure-all.
So I don't really have any fall plans right now. I really wanted to do the River Run HM here in September, but I've put that on hold because I can't really train properly. I may still run it, it just depends on how the next couple of weeks go with my knee ...
And like the rest of the country, Cleveland has been HOT. Even running first thing in the morning, I've had several runs where it was in the very high 70s to low 80s to start. I still like that weather better than snow.
