I hadn't run for a couple of weeks as I was skiing last week (I know, lucky me) and for a couple of weeks before that I was concentrating on squats and lunges in the gym. Well, that all worked out ok, fitness-wise. Tried a run on Tuesday and managed just a slow 2.5k. Got the right leg pain that I hadn't felt since my previous run. Think I may have to see a physiotherapist.
