Puerto de Cerredo

Puerto de Cerredo cycling climb profile

Puerto de Cerredo is a compact, highly concentrated climbing effort. On paper, 6.7km does not sound especially long, but the average gradient of 10.16% changes the physiology of the ride immediately. This is not a climb where distance is the main limiter. The limiter is torque, traction, and the ability to keep power under control when the road stops giving you recovery.

The climb starts at 559m and rises to 1238m, gaining 679m from bottom to summit. That tells the story clearly: almost every part of the route is working against you. A category 1 rating fits the profile because the difficulty comes from how much elevation is packed into such a short distance.

How the gradient rides

With only 6.7km to cover and a 10.16% average, Puerto de Cerredo should be treated as steep from the lower slopes rather than as a climb that gradually becomes selective. The average is already high enough that any easier stretch, if present, would have to be paid back by steeper road elsewhere.

The headline figure is the 32.34% maximum gradient. That number matters less as a standalone shock and more because of what it does to pacing. On a climb averaging over 10%, a ramp that steep can force riders out of rhythm, push cadence down, and turn a steady threshold effort into repeated muscular surges. If you arrive at that kind of pitch already overcommitted, the rest of the climb becomes damage limitation.

Pacing and gearing notes

The right approach is conservative early, even if the opening feels manageable. On a climb this steep, riding just a little too hard at the bottom compounds quickly because there is limited room to recover while still moving efficiently.

Use a gear that lets you preserve cadence before the steepest sections rather than waiting until the road forces the shift. The 32.34% maximum gradient makes low gearing a practical requirement, not a comfort choice. Grinding too early will load the legs before the decisive pitches, while over-spinning is unlikely to be the problem on terrain this steep.

For pacing, anchor the effort below your sustainable climbing limit until the final part of the ascent. If using power, this is a climb where discipline around /glossary/ftp matters: the average gradient tempts a hard, seated effort, but the maximum gradient means spikes are almost unavoidable. The goal is to leave enough margin to absorb those spikes without turning the climb into a series of recoveries that never arrive.

Puerto de Cerredo rewards riders who respect the numbers. Short does not mean simple here. At 6.7km, 10.16% average, and a maximum of 32.34%, it is a climb that punishes optimism and favours controlled, geared-down riding from the first kilometre.
