Which way round
Anticlockwise: Climbs 17% for 400 m early on, no steep descents.
Clockwise: Easy first 4.8 km, no steep climbing, comes down 17% for 400 m near the end.
Better anticlockwise: you climb the steeper side (0.4 km at 10%+, 0.4 km of it 15%+) and come down no steep ground. Steep descents are where people slip, and they're harder on knees late in a walk.
Main climb: km 5.2–6.1, from 289 m to 385 m.
