Portillo de Peña Escalera

Overview

The Portillo de Peña Escalera is a category 2 climb that covers 8.4 km at an average gradient of 5.47%. It begins at 559 m and tops out at 1017 m, giving a net elevation gain of 458 m, with the recorded total ascent sitting at 434 m. That average of 5.47% places it firmly in the mid-tier of mountain efforts — long enough to demand a real strategy, but not so steep that it becomes a pure survival grind. The headline number to respect is the 11.26% maximum gradient, a pitch more than double the average that will punish anyone who arrives at it already in the red.

How the Gradient Unfolds

Read the two key figures together and the shape of the climb comes into focus. An average of 5.47% spread across 8.4 km, with spikes reaching 11.26%, tells you this is not an even, metronomic slope. Instead, the gradient breathes: stretches sitting near or below the 5.47% mean are offset by sharper ramps that drag the effort up toward that 11.26% ceiling. The 458 m of vertical gain is delivered unevenly, so the smart move is to treat the average as a budget rather than a target — bank a little where the road eases, and be ready to absorb the steeper kicks without blowing your rhythm apart.

Pacing Notes

Over 8.4 km, sustainable power matters far more than heroics on the first ramp. Anchor your effort to your FTP and aim to hold a steady percentage of it for the full climb, letting your output rise only on the pitches toward 11.26% and settle again on the shallower sections. If you are not sure what wattage a climb this length can bear, run your recent numbers through the FTP estimator before you commit to a target. A climb averaging 5.47% rewards even effort: going too hard early, before the steeper ramps arrive, is the classic way to turn a manageable 458 m of climbing into a painful one.

Gearing

For a category 2 climb of this profile, a compact setup is the sensible default. A 34×32 lowest ratio will handle most of the 8.4 km comfortably, keeping your cadence up on the sections around the 5.47% average. But because the gradient touches 11.26%, having a 34×34 in reserve is genuinely worthwhile — that extra sprocket is the difference between spinning over the steep ramps and grinding to a near-stall. If your legs are fresh and your fitness is strong, 34×32 is plenty; if you value spin and want insurance against the 11.26% pitches, choose 34×34.

Summary

The Portillo de Peña Escalera is an honest, well-rounded category 2 test: 8.4 km, a 5.47% average, and just enough steep ramps up to 11.26% to keep you honest. Pace it to your FTP, gear for the kicks, and the 458 m of climbing will reward a rider who stays composed.
