Which way round

Clockwise: Climbs 22% for 2880 m midway, comes down 26% for 1700 m near the end.

Anticlockwise: Climbs 26% for 1700 m early on, comes down 22% for 2880 m midway.

Better clockwise: you climb the steeper side (7.2 km at 10%+, 7.2 km of it 15%+) and come down 3.6 km of steep ground. Steep descents are where people slip, and they're harder on knees late in a walk.
