Puerto de los Santos

Overview

Puerto de los Santos is a 7.8 km category 3 climb that gains 325 m of net elevation, lifting you from a start at 635 m to a summit at 960 m. On paper the 4.18% average gradient reads as a moderate, rhythmic ascent — the kind of climb where you settle into a steady tempo rather than survive from switchback to switchback. But with a maximum pitch of 8.05%, there is enough variation to keep you honest. This is a climb of shape and cadence, not brute suffering: consistent enough to reward a diesel engine, punchy enough in places to punish a sloppy pace.

How the Gradient Unfolds

The headline figure is a 4.18% average across 7.8 km, but the gap between that average and the 8.05% maximum tells the real story. A climb that averaged its steepest gradient the whole way would gain far more than 325 m over this distance, so the steep sections are localised ramps rather than sustained walls. Expect the road to breathe — stretches that sit comfortably below the average, offset by short kickers that push toward the 8.05% ceiling. The distinction between the 325 m net gain and the 311 m total ascent is small, just 14 m, which confirms the profile climbs almost continuously with little to no descending or false-flat give-back. In other words, once you start climbing, you keep climbing.

Pacing Notes

Because the gradient rarely spikes for long, Puerto de los Santos suits a steady, threshold-adjacent effort. Aim to hold a pace you can sustain for the full 7.8 km rather than blowing your budget on the ramps toward 8.05%. If you know your FTP, target a percentage of it that leaves headroom for the steeper pitches — riding just under threshold on the shallower sections and letting your power drift up over the kickers keeps your effort even. Not sure where your threshold sits? Run the numbers through the FTP estimator before you attempt it. The key is to arrive at each steep ramp with something in reserve, so the 8.05% moments feel like accents rather than crises.

Gearing

With a 4.18% average and pitches to 8.05%, most riders will be comfortable on a compact setup. A 34×32 gives you a reliable spinning gear for the sustained tempo sections and covers the majority of the ramps without forcing you out of the saddle. If you prefer to keep your cadence high or you're carrying fatigue, stepping up to a 34×34 buys extra insurance for the steepest 8.05% pitches, letting you sit and spin rather than grind. Neither the length nor the gradient demands anything more extreme — this is a climb where the right gear is about protecting your rhythm, not just surviving.

Summary

Puerto de los Santos is an honest, rhythmic category 3 ascent: long enough to matter at 7.8 km, steady enough at 4.18% to reward pacing, and spiced with pitches to 8.05% that keep it interesting. Nail your effort, pick the right gear, and it rides beautifully.
