Thanks again for the advice Travs. Actually, I think I'll stick to the longer distances for a while as the 2000 sprint was definitely tough. I don't think it did my overall fitness a good turn
but at least the tinatus has now gone!
I've a day off work tomorrow, so its the 10000m again before breakfast (I'm going to see if I can clock up 30 miles a week as my fell running target had been) to set me up for the day ahead on the fells - walking unfortunately until the ankle injury is back to normal. Speaking of which, how is the calf muscle?
