Alto del Higuerón

Overview

Alto del Higuerón is a Category 1 climb that packs a serious punch into a compact 8.2 km. It starts at 896 m and finishes at 1693 m, a summit elevation that puts you well into thin-air territory by the time you crest. The headline number is the average gradient: 9.76% sustained over the full length. That is not a figure with soft spots baked in — it is a genuinely steep road that asks for respect from the first pedal stroke.

The net elevation gain is 797 m, while the total ascent measured along the road registers 772 m. With a maximum gradient touching 19.09%, this is a climb where the hardest ramps come close to doubling the average. On a 1 (one) category scale where HC is the hardest, then 1, 2, 3, 4, the Category 1 rating tells you exactly what to expect: a climb that will hurt.

How the Gradient Unfolds

The defining feature of Higuerón is relentlessness. Across 8.2 km, a 9.76% average leaves almost nowhere to coast and recover. The road hauls you from 896 m to 1693 m — a 797 m rise — with the gradient rarely dipping into single-digit relief.

The spike to 19.09% is the moment to circle in your memory. That maximum is nearly twice the average, meaning the steepest pitch is roughly 9.33 percentage points above the mean grade. Ramps like that torch your legs quickly if you hit them with too much speed already banked. Between those pitches, the road settles back toward the high-single-digit and low-teens gradients that define the bulk of the climb — steep enough that "settling back" is relative.

Pacing Notes

On a climb this steep and this sustained, pacing is everything. The 9.76% average over 8.2 km means you will be near your ceiling for the entire effort, so anchor your intensity to your FTP rather than to how you feel in the opening kilometre — where fresh legs lie to you.

If you do not know your threshold, run the numbers first with the FTP estimator. Aim to hold a steady percentage of that number on the sustained 9.76% sections, then accept a brief surge above threshold when the road spikes toward 19.09%. Trying to hold a constant speed here is a trap; hold a constant effort and let your pace sag on the ramps. With 797 m still to climb once you commit, going into the red early on Higuerón means paying it back with interest before 1693 m.

Gearing

Steepness this severe rewrites your gearing math. For most riders, a compact 34-tooth chainring paired with a wide cassette is the sensible starting point. A 34×32 will get many strong climbers up the 9.76% average, but on the 19.09% ramps that ratio can force you into grinding, high-torque efforts that drain your legs.

If you have any doubt about your climbing power, go bigger at the back: a 34×34 buys you the extra spin to keep cadence alive on the steepest pitches and protects your knees over the full 8.2 km. Given the 797 m of gain, the marginal weight of a larger cassette is nothing next to the fatigue you save.

Summary

Alto del Higuerón is a short, savage Category 1 test — 8.2 km that never eases, climbing 797 m to a 1693 m summit at an unforgiving 9.76% average. Gear low, pace to your threshold, and save something for the 19.09% ramps.
