Which way round
Anticlockwise: Easy first 2.5 km, climbs 15% for 250 m early on, comes down 20% for 250 m early on.
Clockwise: Climbs 20% for 250 m near the end, comes down 15% for 250 m near the end.
Better clockwise: you climb the steeper side (0.5 km at 10%+, 0.5 km of it 15%+) and come down 0.3 km of steep ground. Steep descents are where people slip, and they're harder on knees late in a walk.
Main climb: km 12.4–13.4, from 18 m to 90 m.
