Puerto Aceituno

Overview

Puerto Aceituno is a Category 2 climb in Spain, running 22.4 km from a start elevation of 595 m to a summit at 1,511 m. Across that distance it delivers a net elevation gain of 916 m at an average gradient of 4.08%. On paper that average reads as a steady, manageable drag, but the length alone means it demands real endurance rather than a short, punchy effort.

The more telling number is the gap between net gain and total work done. While the climb only lifts you 916 m from bottom to top, the total ascent is 2,159 m. That means roughly 1,243 m of climbing is spent regaining ground lost to descents and dips along the way. This is an undulating profile, not a smooth ramp, and the repeated up-and-down costs far more energy than the modest net figure suggests.

How the Gradient Unfolds

The 4.08% average is a blend, not a constant. It masks flatter recovery stretches and false flats offset by markedly steeper pitches, culminating in a maximum gradient of 23.36% — a wall that will force you out of the saddle or into your lowest gear. Expect the effort to arrive in bursts rather than as one long grind.

• Flatter and mildly descending sections where you can recover and roll
• Repeated short climbs that each re-add elevation lost on the dips
• A steepest ramp hitting 23.36%, well above anything the average implies

Pacing Notes

On a smooth climb you could hold even effort and let speed drift with the slope. Here the undulation complicates that. Chasing an even speed will spike your power on every steep kicker and blow you up early. Instead, anchor your effort to a target sustainable power output and let your speed rise and fall with the terrain — ease slightly on the ramps, press on the flatter recovery sections. Use the descents to genuinely soft-pedal and clear your legs before the next rise. If you don't know your numbers, run the FTP estimator first so your pacing target is grounded in real data.

Gearing

The 23.36% maximum gradient governs your setup, not the gentle average. That pitch is steep enough to stall a standard chainset. Fit a compact or sub-compact crank and pair it with a wide-range cassette — 34×32 or 34×34 gives you the low gear to keep cadence up rather than grinding to a near-stop. Check your setup before the ride; discovering you're over-geared halfway up a 23% wall is a mistake you only make once.

Summary

• Length: 22.4 km
• Average gradient: 4.08%
• Maximum gradient: 23.36%
• Net elevation gain: 916 m
• Total ascent: 2,159 m
• Category: 2

Puerto Aceituno is a climb defined by its undulation. The modest average and net gain understate the 2,159 m of total ascent you'll actually turn over. Pace to power, gear for the 23.36% ramp, and treat every descent as recovery for the next rise.
