I have had IT band issues on and off since running the Chicago Marathon in October. I just ran 10 miles yesterday - the last long run before the Disney Half this Saturday. My knee is now really bad. I'm rolling it and taking anti-inflammatories, but I'm concerned about my chances of finishing the half pain free. I just bought one of those straps for knees - thinking that might help. Has anyone ever used one for this and, if so, did it help? Any other ideas to get me through the half?
