Ok, I am typing this in a wee bit of pain. I've just come back from a run. Time and distance all relatively easy and it should have been a breeze BUT about half way in I had the worst pain in both my feet. So much so that I had to physically stop moving and check I hadn't just ran over 5 inch deep broken glass without trainers on. I do have a foot injury anyway, but this pain was nothing to do with that as it happened in both feet and was a completely different feeling. The only explanation I have for this it, was that it was my first serious run 'off piste', normally I am a bit of a concrete runner. But since moving out of London and back to the country I thought I'd try a bit of outward bound. So my question is, was this muscular foot strain due to virgin feet on rough dry terrain, or have I busted myself??
