pace run 48:00 
Muir of Dinnet - from visitor centre car park, across road, parallel to east then cross road and wound my way up the hills to NW, occasional stops to retie laces and catch my breath but all decent going, avoiding heather and bracken as much as possible. One small hill had me wading through waist deep heather then turned left towards burn and back down gorge (forgotten how slow going down the gorge is!).
left calf fine, hardly a tweak from it. Terrain is good :-)
Physio exercises 14:00
