Which way round
Anticlockwise: Easy first 12.2 km, climbs 15% for 350 m near the end, comes down 18% for 200 m near the end.
Clockwise: Easy first 4.8 km, climbs 18% for 200 m early on, comes down 15% for 350 m early on.
Better anticlockwise: you climb the steeper side (0.5 km at 10%+, 0.2 km of it 15%+) and come down 0.2 km of steep ground. Steep descents are where people slip, and they're harder on knees late in a walk.
Main climb: km 12.2–12.8, from 65 m to 128 m.
