Went for a longish ride today, nothing too arduous, just an 80km odd MTB road ride in London taken at a reasonably leisurely pace (avg 23km/hr). All fine on the ride, but now I've cooled down I have a sharp 'twinge' in my left knee - it's in the front, just below the kneecap, worst when I'm climbing stairs or rising up from a squat, fine to walk on...
just a little sore from my first 'long' ride in a while, or something I should look into before continuing my MM soloist build-up? Not had this before, so unsure what it might be...
