Just completed 0-5k with a club which was great but although nothing hurts while running I get lots of stiffness and pain in my hip for the next few days. I am 53 and about 1 stone overweight so I'm sure that's not helpful!! But I don't know whether to keep running or rest until it stops hurting! I walk about 25 miles a week ( active job and dog walking) and running 5k twice a week. Pretty slowly about 33 / 34 minutes. Fed up I can't walk up the stairs without pain for 48 hours after running. Any advice?
