Puerto del Comendador

Overview

Puerto del Comendador is a Category 4 climb in Spain, running 7.3 km from a start elevation of 815 m to a summit of 1051 m. Over that distance it delivers a net elevation gain of 236 m, giving it a moderate average gradient of 3.22%. This is a road you climb in a rhythm rather than a fight — long enough to matter, shallow enough on paper to underrate.

The number worth watching is the gap between net gain and total ascent. You gain 236 m of altitude, but you actually climb 274 m — an extra 38 m of ascent that comes back as short descents and false flats along the way. That undulation means the climb is not a single steady drag. You will do more work than the net figure suggests, and every metre you give back on a dip has to be re-earned. Budget for it.

How the Gradient Unfolds

The 3.22% average is a blend, not a description of any single kilometre. On a rolling profile like this, some sections sit well below average — even flat or slightly downhill — which forces the climbing pitches above the mean to compensate. The steepest ramp on the climb hits 10.5%, more than three times the average.

• Flatter and recovery sections where the road eases or briefly tips downhill
• Repeated short climbs that build back the elevation lost on each dip
• A steepest ramp of 10.5% that demands a gear and a burst of effort

Pacing Notes

On an undulating climb, chasing an even speed is a trap: you would burn matches on every rise to hold a number that means nothing here. Pace to effort instead. Aim to hold a steady sustainable power output across the whole climb, letting your speed rise on the descents and false flats and fall on the ramps. On the 10.5% pitch, allow the effort to spike briefly rather than blowing your whole ceiling to keep it smooth. If you do not know your ceiling, run the FTP estimator before you ride so your target is grounded in real numbers.

Gearing

The 3.22% average will not dictate your setup — the 10.5% ramp will. Come with a compact or sub-compact chainset and a wide-range cassette so you can spin the steep section rather than grind it. A 34×32 will cover most riders here; a 34×34 gives more margin on tired legs or a loaded bike. Check your chainset and cassette before the ride, not at the base of the climb.

Summary

• Length: 7.3 km
• Average gradient: 3.22%
• Maximum gradient: 10.5%
• Net elevation gain: 236 m
• Total ascent: 274 m
• Category: 4

Puerto del Comendador rewards riders who read the profile rather than the average. Pace to effort, gear for the 10.5% ramp, and account for the 38 m of ascent hidden in the undulation, and it climbs cleanly from base to summit.
