Col de Perjuret

Col de Perjuret cycling climb profile

The Col de Perjuret is a Category 1 climb in France that asks for patience more than aggression. On paper, the core shape is clear: 12.9 km at an average gradient of 5.72%, starting at 356 m and topping out at 1092 m. That gives it the feel of a long aerobic climb rather than a short threshold test, but the 12.48% maximum gradient is the number that should shape how you ride it.

The average tells you the climb is manageable if paced correctly. The maximum tells you that treating the lower slopes like a tempo warm-up can become expensive later. With 736 m of net elevation gain between bottom and summit, the road has to keep asking for work for a long time. Even if sections feel controlled, the climb is still accumulating load steadily.

How the gradient plays out

With only the full-climb figures, the safest reading is that Col de Perjuret is not defined by one brutal wall, but by the contrast between a moderate overall gradient and short sections steep enough to disrupt rhythm. A 5.72% average over 12.9 km rewards a seated, efficient effort. The 12.48% maximum gradient means there are moments where cadence can collapse if you arrive overgeared or already above target.

That combination matters tactically. Riders who chase speed early can end up paying twice: first by pushing above sustainable power on the steeper pitches, then by losing smoothness when the climb settles back into its longer grind. The better approach is to keep the effort boringly controlled through the opening part and save the harder accelerations for the upper slopes, once the remaining distance is no longer dictating the ride.

Pacing and gearing notes

Use the average gradient as your pacing anchor, but gear for the maximum gradient. For most riders, this is a climb where a compact or sub-compact setup makes sense, not because the whole climb is severe, but because the steepest ramps reach 12.48%. Having one easier gear than you expect to need helps protect cadence when the road kicks up.

Practical pacing:

• Ride the first half below your target climbing effort, especially if you are using /glossary/ftp as your reference.
• Stay seated where possible and keep torque under control on the steeper ramps.
• Avoid responding to every change in pitch. The climb is long enough that smooth power matters more than short bursts.
• If you feel strong near the summit, lift the effort late rather than trying to force the climb from the bottom.

The Col de Perjuret is difficult because it is long enough to punish impatience and steep enough in places to punish poor gearing. Respect both numbers - 12.9 km and 12.48% - and it becomes a climb you can ride with control rather than survive by correction.
