Puerto de La Estaca

Overview

Puerto de La Estaca is a short, honest climb that hides very little. Over 3.4 km the road lifts you from 15 m at the base to 235 m at the summit, a net gain of 220 m at an average gradient of 6.56%. That average is steep enough to keep you working the whole way, and with a maximum pitch of 8.85% there is a real sting somewhere in the middle. This is a category 3 effort — not a mountain giant like an hors catégorie pass, but far from a warm-up. It rewards riders who can hold a firm tempo and punish those who start too hard.

How the Gradient Unfolds

The shape here is compact and consistent. With a 6.56% average and an 8.85% maximum, the spread between typical and hardest is modest — only about 2.29 percentage points. That tells you the road never truly relents into a false flat, nor does it rear into a wall you have to survive. Instead you get a steady grind that firms up toward its steepest 8.85% ramp before easing back toward the summit. Note the small gap between the 220 m net gain and the 203 m of total ascent: the profile is almost entirely uphill, with very little rolling relief to break the rhythm. Once you start climbing, you keep climbing.

Pacing Notes

On a climb this short, the temptation is to attack from the bottom — resist it. At 3.4 km you will be at the top in a matter of minutes, but 6.56% sustained is enough to bury you if you overcook the opening. Aim to sit just under your threshold and let the 8.85% pitch be where you spend your matches, not the flatter opening metres.

Anchor your effort to your FTP. Riding the bulk of the climb slightly below threshold, then lifting over the steepest section, gets you to 235 m fastest without blowing up. If you are unsure of your number, run the FTP estimator first and set a realistic ceiling before you tackle the 8.85% ramp.

Gearing

For a 3.4 km climb averaging 6.56% with pitches to 8.85%, most riders will be well served by a compact setup. A 34×32 gives you enough range to spin the steepest ramp without grinding, and if you favour a higher cadence or carry fatigue into the effort, dropping to a 34×34 buys extra insurance on that 8.85% section. Neither is overkill on a category 3 climb — the smoother you can pedal the steep pitch, the fresher you arrive at 235 m. If you race, you might hold a tighter ratio, but for repeatable efforts the compact and wide cassette combination is the smart, sustainable choice.

Summary

Puerto de La Estaca is a sharp, well-defined climb: 3.4 km, 220 m of net gain, and a steady 6.56% that never lets you coast. Get your pacing right, pick a gear that keeps you spinning through the 8.85% pitch, and it becomes a satisfying test of controlled effort.
