I decided to try my first run since the marathon. Everything has been feeling good but I figured I'd be happy if I could make it a mile before my hip flexor would get sore. I was amazed to end up going 3 miles without it bothering me. That was as far as my longest run 3 days before the marathon and I was on lots of ibuprofen for that run and it started giving me pain at the end. Today no meds and I felt like I could have kept running but decided to play it safe. This is encouraging and looks like I didn't set back my recovery from this hip flexor thing by more than a week or two by running the marathon. 8:07 ave pace.
