Col du Jorat

Col du Jorat cycling climb profile

The Col du Jorat is classified as an HC climb, and the numbers justify that label. At 13.2 km with an average gradient of 7.85%, it is long enough that the main difficulty is not one isolated steep section, but the accumulation of sustained climbing. The road rises from 465 m to 1500 m, which means the vertical gain is doing its damage over a relatively compact distance.

This is the kind of climb where the average gradient matters more than the headline maximum. A max gradient of 11.52% is steep, but it is not wildly detached from the 7.85% average. That tells you the climb should be approached as persistently hard rather than as a gentle climb with a few violent ramps. If there is recovery, the profile data does not suggest it is the defining feature.

How the gradient unfolds

From bottom to summit, the practical reading is straightforward: settle early, because the climb does not give much mathematical room for a reset. A 13.2 km climb at this gradient punishes riders who ride the lower slopes like a short effort. The opening should feel controlled enough that breathing and cadence are still sustainable, not already forced.

As the climb continues, the challenge becomes torque management. With the steepest pitches reaching 11.52%, there will be moments where the road asks for more force through the pedals. Those sections are best treated as pressure points, not invitations to surge. If you lift the effort every time the gradient bites, the cost compounds quickly over this length.

The final part of a climb like this is usually where pacing discipline shows. The elevation gain has been large enough by then that any early overreach becomes obvious. The best ride is likely to feel slightly conservative in the first half and increasingly deliberate toward the summit.

Pacing and gearing notes

Use the 7.85% average to set the day’s effort, but choose gearing for the 11.52% maximum. That distinction matters. Pacing for the average keeps the engine under control; gearing for the steepest ramps keeps cadence from collapsing when the road pitches up.

A good target is a steady climbing rhythm just under the effort you associate with a long threshold climb. If you know your /glossary/ftp, this is a climb where that number should inform restraint rather than aggression. The cost of going too deep early is high because there is still a lot of road left after the first hard minutes.

In practical terms, arrive with a low enough gear that you can stay seated through the steepest parts without grinding. Standing can help reset the legs, but it should not become the default response to every ramp. On the Col du Jorat, efficiency matters because the climb’s difficulty comes from duration plus gradient, not from a single decisive wall.
