Puerto de Payares

Overview

Puerto de Payares is a category 2 climb in Spain, running 8.9 km from a start elevation of 952 m to a summit at 1376 m. On paper, its 424 m of net elevation gain and 4.78% average gradient read as a manageable middle-tier ascent — the kind of climb you can settle into and grind out at tempo.

That reading is incomplete. The total ascent over the 8.9 km is 1013 m, which is more than double the 424 m net gain. That 589 m gap means the road repeatedly climbs and gives elevation back — you are pedaling uphill far more than the net figure suggests. The undulation inflates the real effort well beyond what the average gradient implies, and it punishes riders who pace by the summit height alone.

How the Gradient Unfolds

The 4.78% average is an accounting artifact. It blends genuinely steep pitches with descents and flatter recovery, so almost no section of the road actually feels like 4.78%. The standout number is the maximum gradient of 24.24% — a wall-like ramp that will overwhelm any rider who arrives at it already redlined.

Across the profile, expect:

• Flatter and false-flat sections that let you recover but also flatter your average
• Repeated short climbs where the road claws back elevation it just surrendered
• At least one severe ramp topping out at 24.24%, steep enough to force you out of the saddle

Pacing Notes

Do not pace this climb by even speed — the undulation makes constant speed impossible and constant chasing of it will blow you up. Pace by even effort instead, holding a steady sustainable power output through the flats and easier grades, then accepting that the steep ramps will spike your power briefly above that ceiling.

The recovery sections are your friends: spin easy and let your heart rate settle before the next pitch rather than hammering to hold speed. If you do not know your ceiling, run the FTP estimator first so you have a real number to anchor the effort against, not a guess.

Gearing

The 24.24% maximum gradient dictates your setup, not the gentle average. On a ramp that steep, an under-geared bike leaves you grinding at low cadence or track-standing to a halt. Fit a compact or sub-compact chainset and pair it with a wide-range cassette — a 34×32 or 34×34 low gear gives you a survivable cadence when the road stands up. Check your chainset and cassette before you ride; discovering you are one sprocket short halfway up a 24% wall is not the place to find out.

Summary

• Length: 8.9 km
• Average gradient: 4.78%
• Maximum gradient: 24.24%
• Net elevation gain: 424 m
• Total ascent: 1013 m
• Category: 2

Puerto de Payares is a climb that rewards riders who read past the average. Respect the undulation, gear for the steepest ramp, and pace by effort — do that, and the 4.78% average stops being a trap.
