Portilla de la Canda

Overview

Portilla de la Canda is a category 3 climb in Spain, running 8 km from a start elevation of 966 m to a summit at 1258 m. The net elevation gain across that distance is 292 m, which puts its average gradient in gentle territory. On paper it reads as a steady, moderate ascent, and for a rider judging it by the category alone, that is roughly the expectation to bring to the start.

The number that reshapes the story is the total ascent: 451 m against a net gain of only 292 m. That 159 m gap is climbing you do twice, giving back elevation you already earned before taking it again. This climb undulates rather than rises cleanly, so the effort is meaningfully harder than the net figures suggest. Every metre of descent inside the climb is a metre you re-climb, and a pacing plan built on the average gradient will leave you short.

How the Gradient Unfolds

The 3.64% average is a blend, not a description of the road. With a maximum gradient of 18.15%, the climb hides real steepness behind stretches of flat and downhill that pull the average down. Expect the road to change character repeatedly rather than settle into a rhythm.

• Flatter and recovery sections, including short descents, that account for the gap between net and total ascent
• Repeated short climbs that stack up to 451 m of ascending over the 8 km
• A steepest ramp reaching 18.15%, far above the average and where the day is decided

Pacing Notes

On a smooth climb you can hold even effort and let speed drift. Here, the undulation forces a choice. Chasing even speed means overcooking the 18.15% ramp and the short climbs; chasing even effort means easing on the flatter and downhill sections. Pace to a target sustainable power output, not to a speed on the display. Let power fall on the descents, spin the recovery sections, and save your matches for the steep pitches. Know your ceiling before you start with the FTP estimator.

Gearing

The 18.15% maximum governs your setup, not the 3.64% average. Fit a compact or sub-compact chainset with a wide-range cassette so you can keep cadence up when the road kicks. A 34×32 handles most of it; 34×34 gives more margin for tired legs late on the repeated climbs. Check your setup before the ride, because the steepest ramp is where an undersized gear will force you out of the saddle and burn matches you cannot afford.

Summary

• Length: 8 km
• Average gradient: 3.64%
• Maximum gradient: 18.15%
• Net elevation gain: 292 m
• Total ascent: 451 m
• Category: 3

Portilla de la Canda rewards riders who read past the average. Pace to power, gear for the 18.15% ramp, and treat the 159 m of extra ascent as the real test of the day.
