Puerto de Padornelo

Overview

Puerto de Padornelo is a category 3 climb in Spain, running 9.2 km from a start elevation of 1,015 m to a summit at 1,376 m. On paper it is modest: a net elevation gain of 361 m over that distance works out to a gentle average, and the summit sits just under 1,400 m. It is the kind of pass that reads as a warm-up on a route sheet rather than a headline objective.

The number that matters, though, is the gap between net gain and total ascent. You climb 361 m net, but the road actually asks for 652 m of total ascent — roughly 291 m of that is climbing you do only to give it straight back on intervening descents. That undulation means the effort is lumpier than the average gradient implies. You are not settling into one long, steady drag; you are repeatedly lifting your speed back up after every dip, and that costs more energy than a smooth 9.2 km at the same net grade would.

How the Gradient Unfolds

The 3.93% average is an artifact of all that up-and-down, not a description of the road under your wheels. Because 291 m of ascent is absorbed by descents, the climbing pitches must be steeper than 3.93% to still net out where they do — and the profile tops out at a 13.41% ramp.

• Flatter and downhill recovery sections where the road gives back elevation between rises.
• Repeated short climbs stacked back-to-back rather than one continuous gradient.
• A steepest ramp of 13.41% that is far harder than the average suggests — anticipate it.

Pacing Notes

Do not chase even speed here; the descents will let you coast and the rises will spike your effort if you try to hold a fixed pace. Instead, pace to even effort. Hold a steady, sustainable power output through the climbing pitches and let your speed rise and fall with the terrain — soft-pedal the dips, push the ramps only as hard as your target effort allows. On a climb with this much undulation, even-effort pacing is what keeps the repeated re-accelerations from quietly burning your matches. If you are unsure what number to hold, run the FTP estimator first and set a ceiling you can carry across all 9.2 km.

Gearing

The 13.41% ramp is what dictates your setup, not the friendly average. Fit a compact or sub-compact chainset and pair it with a wide-range cassette — a 34×32 or 34×34 low gear gives you a cadence you can turn over on the steepest pitch without grinding to a stall. Check your setup before the ride: confirm the chain reaches the largest sprocket cleanly and shifts under load, because the steep sections here arrive after you have already spent energy on the rollers.

Summary

• Length: 9.2 km
• Average gradient: 3.93%
• Maximum gradient: 13.41%
• Net elevation gain: 361 m
• Total ascent: 652 m
• Category: 3

Puerto de Padornelo rewards riders who read past the average. Pace to effort, gear for the 13.41% ramp, and treat the 291 m of hidden climbing as the real workload rather than the gentle net gain on the profile.
