Puerto de Buenavista

Overview

Puerto de Buenavista is a short, uncompromising climb that packs a lot of vertical into very little road. Over just 5.4 km it gains 421 m net, rising from 1881 m at the base to a summit of 2302 m. That works out to an average gradient of 7.78%, and with a maximum pitch of 17.94% the profile is steep enough to demand respect from the first pedal stroke. Its Category 2 rating tells the story: not the mythic length of an hors-catégorie monster, but far more than a warm-up. This is a climb you finish out of breath.

How the Gradient Unfolds

The headline number here is the gap between average and maximum. A 7.78% mean is already a sustained grind, but the 17.94% max means the climb is not evenly paved with effort — there are ramps that more than double the average. Expect the road to lurch upward in places, with the steepest ramp roughly ten points above the mean. With a total ascent of 403 m recorded against 421 m of net gain, the road climbs almost relentlessly from bottom to top; there is very little false-flat or descent to recover on. Treat every kilometre as climbing kilometre and save nothing for a plateau that never really arrives.

Pacing Notes

Because the climb is short and steep, pacing is about not overcooking the early ramps. Anchor your effort to your FTP: on a 5.4 km Category 2 wall you can ride meaningfully above threshold, but the 17.94% pitches will spike your power far higher than the 7.78% average suggests, so leave a buffer for them. If you do not know your threshold, run the numbers through the FTP estimator before you tackle this one. The smart approach is a steady, slightly conservative tempo on the shallower sections, then accept a surge on the steepest ramps rather than trying to hold a fixed power — grinding to a near-stall on a 17.94% pitch costs far more than a brief, controlled effort over it.

Gearing

Steepness, not length, dictates gear choice on Puerto de Buenavista. With ramps hitting 17.94%, you want low, low gearing to keep your cadence alive. A compact 34-tooth inner chainring is the sensible foundation. Pair it with at least a 34×32 for the sustained 7.78% sections, and if you have the range, a 34×34 is the safer call for the steepest pitches — that extra sprocket is the difference between spinning and lurching when the road stands up. Stronger climbers may cope with 34×32, but nobody regrets the bailout gear on a wall like this.

Summary

Puerto de Buenavista is a concentrated, honest climb: short enough to attack, steep enough to hurt. Gear low, pace the ramps, and respect the gap between its 7.78% average and 17.94% maximum, and you will crest the 2302 m summit having earned every metre of the 421 m gain.
