Discussion: Take it easy...

...no point in aggravating it! As tempting as it might be to go out and slaughter yourself this week, discretion is the better part of valour...

I know: the prescription is for some easy running, no heroics.

Good man, sounded like a bit of a tough day at the office yesterday, especially when you don't know why it happened. Remember it was only 2 weeks or so ago that you were nearly winning a major fell race, so get yourself healthy and you'll be in a good spot. Looking forward to seeing you have a proper go at a marathon!
