Grade: 1
Tightening up on long runs. 1 week rest. Swimming allowed.
Fairly persistent as a vague ache towards the end of a run.
Probably overtraining. I've tried to mix the training and not push too hard Physio has helped a lot massaging the lumps, and did a strenuous run today with no ill-effects. Took a while to get rid of but was never severe. Both hamstrings still tight - trying to loosen them with Pilates
