The climb
Col de Pertus climbs 4.4 km at an average of 8.5%, gaining 374 m to a summit at 1,309 m. The average hides a lot: the kilometres swing widely either side of it, so the climb is a sequence of ramps and easier stretches rather than a constant effort.
The hardest kilometre measures 10.9% and comes in the opening third of the climb, and 3 kilometres of the ascent average more than 8%, one of them above 10%. The final kilometre eases to 6.0%, which is where the climb gives something back.
