Just back from a Sunday long run (15k) and had a fair bit of hip pain just in one side which started at about 7-8k. I've had this before on a long run (both hips then) and it only hurts whilst running. It was frustrating today as my breathing and my legs were good, and this was the only thing that caused me problems.
I found that if I stopped for a few minutes and stretched and generally slapped and rubbed my hip I was able to carry on for a bit further before I repeated the process.
No reals problems now (post run) but I dosed up on ibuprofen just in case.
I'm going to have a word with a friend who's a Physio tomorrow and get her opinion.
Has anyone else had similar problems???
