I am only 3 months into regular running. I ran years ago and battled through sore feet and knees. I've since had bunion surgery and knee pain cured......until my long run!! I did 13k this Sunday and had a slight left knee niggle during the run, but burning knees for the hours after and stiffness (I do have arthritis). Today I have absolutely no knee pain at all. I do other exercise, i.e spinning, weight workouts. Is this sort of pain just because of the distance (I have slowly built up to 13k) and the newness of it all? As I said 24hrs later zero pain.
Any suggestions/advice gratefully received.
