Which way round
Anticlockwise: Climbs 23% for 330 m early on, comes down 27% for 800 m midway.
Clockwise: Easy first 3.1 km, climbs 27% for 800 m midway, comes down 23% for 330 m near the end.
Better clockwise: you climb the steeper side (0.8 km at 10%+, 0.8 km of it 15%+) and come down 0.6 km of steep ground. Steep descents are where people slip, and they're harder on knees late in a walk.
Main climb: km 3.1–5.1, from 636 m to 899 m.
