Orienteering - easy 29:00 [2]
(injured) shoes: Walsh PB racer
Loch Vaa in the snow. Middle distance, got nearly to end then felt sudden pain in left calf (top, inside). Not sure if tear or cramp from the cold, but stopped straight away.
Technically shaky in parts, more so near to the end. Low fitness level and easily distracted > not concentrating enough.
Tough in the long heather, felt I had okay strength but not endurance.
