so my foot is sore. it is sore around the bottom of the ankle and around the top of the foot where it connects to the leg.
it got sore doing a tempo run. i had to cut it short. the day before i had done a long run (longer than it should have been), and day before had done a short duathlon 1.8k run, 10 k bike, 1.8 k run. i was wearing my ds trainers during my tempo run (i wear kayanos on longer non speed oriented runs).
is this likely to be cos my foot isnt strong enough?
