I've started to notice some soreness around and slightly above my hips, which is most noticeable towards the end of, and after the four and a half mile runs I've recently been doing. I'm in the process of joining the Army (fingers crossed), but am coming from a place of little fitness. I've lost a couple of stone over the past three months or so, if that's any help. Is this just a muscle group that I'm working properly for the first time? Today the soreness was almost painful on standing up about half an hour after my run. I'm loath to slow down my training in any way unless I'm properly injured, but don't want to do myself a mischief by overdoing it either. I run on four and a half miles on Monday, Wednesday and Friday, with a 1.5 best effort on Sunday. I've recently increased the distance I run from three and a half miles.
