Puerto de Arteta

Overview

Puerto de Arteta is a category 3 climb in Spain, running 11.1 km from a start elevation of 402 m to a summit at 837 m. On paper it is a modest effort: a net elevation gain of 435 m across those 11.1 km, which produces the gentle 3.94% average gradient you see on the road book.

That average is deceptive. The total ascent is 841 m — nearly double the net gain of 435 m. The 406 m difference means the road falls and rises repeatedly along the way, so you climb far more than the point-to-point profile suggests. Every metre lost to a descent has to be reclaimed, and that undulation is where the real work of this climb hides.

How the Gradient Unfolds

A 3.94% average tells you almost nothing about the effort here. With a maximum gradient of 18.97%, the climb stacks its difficulty into short, sharp pitches separated by flatter ground and descents. Treat the average as a bookkeeping number, not a pacing target.

• Flatter and downhill recovery sections that drag the average down but reset nothing about the ramps ahead
• Repeated short climbs rather than one continuous grind — the profile is a series of punches
• One standout ramp near 18.97%, steep enough to force you out of the saddle if you have geared for the average

Pacing Notes

On a climb this lumpy, chasing an even speed will wreck you — you would surge on every descent and blow up on every ramp. Pace to effort instead. Hold a steady sustainable power output and let your speed rise and fall with the terrain: soft-pedal the descents, and accept a lower pace up the steep pitches rather than spiking your power to hold a number.

The undulation makes discipline harder because the flat and downhill sections tempt you to push. Know your ceiling before you start. Use the FTP estimator to set a realistic threshold, then ride the ramps a touch below it so the 18.97% pitch does not become a max effort.

Gearing

Gear for the steepest ramp, not the average. A near-19% pitch late in an 11.1 km climb demands a compact or sub-compact chainset paired with a wide-range cassette — something like a 34×32 or 34×34 to keep your cadence up when the road kicks. Under-gearing here forces a grinding, muscular effort exactly where the undulation has already cost you. Check your chainset and cassette before the ride; there is no fixing it on the road.

Summary

• Length: 11.1 km
• Average gradient: 3.94%
• Maximum gradient: 18.97%
• Net elevation gain: 435 m
• Total ascent: 841 m
• Category: 3

Puerto de Arteta rewards riders who read past the average. The 3.94% headline is honest arithmetic, but the 841 m of total climbing and the 18.97% ramp are what you will feel in your legs. Gear low, pace to effort, and let the descents do their job.
