Puerto de la Morcuera

Overview

Puerto de la Morcuera is a Category 1 climb in Spain, running 12.1 km from a start elevation of 1068 m to a summit at 1775 m. That gives a net elevation gain of 707 m at an average gradient of 5.84%. On paper it reads as a long, steady tempo effort — a climb you could settle into and grind out at a fixed wattage. The numbers, however, tell a more complicated story.

The gap between the 707 m of net gain and the 985 m of total ascent is the key figure here. That 278 m difference means the road does not climb cleanly to the top: you gain elevation, give some back, and then re-earn it. Every metre lost to a downhill or false flat is a metre you climb twice. The undulation inflates the real work well beyond what the net gain suggests, so plan for an effort heavier than a simple 5.84% average implies.

How the Gradient Unfolds

The 5.84% average is a blend, not a constant. It smooths together descents, flat drags, and pitches far steeper than the mean. Because 278 m of the ascent is recovered ground, the climb arrives in waves rather than one continuous wall.

• Flatter and recovery sections where the road eases or tips downhill — do not coast these away, they set up the next ramp.
• Repeated short climbs stacked between the recovery stretches, each one demanding a fresh surge of effort.
• The steepest ramp, which bites well above the average and will spike your heart rate if you hit it in the wrong gear.

Pacing Notes

On an undulating climb like Morcuera, chase even effort, not even speed. Holding a constant pace forces your power to swing wildly — soaring on the steep ramps, collapsing on the flats. Instead, anchor your ride to a steady sustainable power output and let your speed rise and fall with the terrain.

Let the recovery sections do their job: back off slightly where the gradient relents and bank that headroom for the steeper pitches. Know your ceiling before you start — run the FTP estimator so your target watts reflect real fitness, not optimism. With 278 m of hidden re-climbing, over-cooking the early ramps is the fastest way to blow up before the summit.

Gearing

The steepest ramp governs your gearing here, and it is steep enough that a standard setup will leave you grinding. Fit a compact or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you a bailout gear for the sharpest pitches while keeping cadence high on the sustained sections. Check your chainset and cassette before the ride, not at the bottom of the climb.

Summary

• Length: 12.1 km
• Average gradient: 5.84%
• Maximum gradient: 22.52%
• Net elevation gain: 707 m
• Total ascent: 985 m
• Category: 1

Puerto de la Morcuera rewards riders who respect its undulation. Pace to effort, gear for the steepest ramp, and treat the 985 m of total ascent — not the 707 m net — as the true measure of the day.
