Puerto de Pedro Bernardo

Overview

Puerto de Pedro Bernardo is a Category 2 climb that trades brutality for length. Over 13.2 km it lifts you from a start elevation of 628 m to a summit at 1243 m, a net gain of 615 m. The average gradient of 4.66% places it firmly in tempo territory rather than the leg-snapping steepness of an HC monster, but 13.2 km is long enough that a poorly judged effort will unravel well before the top. Total ascent registers at 598 m, which tells you the road rolls forward with real consistency — there is very little coasting downhill to hand back the metres you have earned.

How the Gradient Unfolds

The defining number here is 4.66%. That is the kind of grade you can hold in the saddle almost indefinitely if your pacing is honest, but the road does not stay pinned to its average. The maximum gradient touches 10.27%, more than double the mean, so expect the climb to lean on you in sharper pitches that break the rhythm before easing back. Because the net gain (615 m) sits just above the total ascent (598 m), the profile is overwhelmingly one-directional: it climbs, and climbs, and only rarely gives anything back. Treat every 10%-ish ramp as a punctuation mark inside an otherwise steady 4.66% sentence, not as the start of a new, harder climb.

Pacing Notes

On a climb this length, the winning move is restraint. Anchor your effort to a percentage of your FTP rather than to how the first kilometre feels — the opening ramps at up to 10.27% will tempt you to overspend before the grade settles. Aim to sit at a sustainable tempo through the 4.66% stretches and accept a short surge over the steeper pitches, then recover as the road relaxes. If you do not know your threshold, run the numbers first with the FTP estimator so you have a wattage ceiling to defend across all 13.2 km. Cresting 1243 m with something left is far more satisfying than blowing up two-thirds of the way up.

Gearing

The 4.66% average is comfortable, but the 10.27% maximum and the sheer 13.2 km duration argue for a little insurance. A compact 34-tooth chainring paired with a 34×32 cassette gives most riders a spin-friendly floor for the steeper ramps while keeping your cadence lively on the tempo sections. If you climb at a lower cadence, carry extra fatigue late, or simply prefer to twiddle, step up to a 34×34. The extra sprocket costs you nothing on a climb where you will never run out of road to grind — and over 615 m of net gain, protecting your knees and your composure pays off.

Summary

Puerto de Pedro Bernardo rewards patience: a long, honest Category 2 ascent that asks for steady power over 13.2 km rather than heroics. Pace it to your threshold, gear for the 10.27% pitches, and let the 4.66% average carry you to the top.
