Witch's tower approach
57 x 175m avg. 53s (42-58s) with 30s rest
Much more ankle-level debris than before. Definitely much slower now southbound than northbound.
No formal rest between sets but due to unanticipated circumstances, took a total of three 3 min rests and three 1 min rests.
Will probably split future sessions into technique (few fast reps with long recovery) and endurance (many slower reps with short recovery).
