Tough night intervals on the tough single track through forest. Was going based on how my calf would feel. Was feeling quite good before so wanted to go for a quality session. Rain cleared but track was sodden.
Managed to complete 3 hard loops about 2km each approx 1mij between each. Pace approx 440, slowed a little on the last. First group was probably 30s per km quicker. Finished off with a slow one. Happy that calf was good, impressed by the pace of the others, clearly lots of room for improvement:
