La Cruz de Bárcena

Overview

La Cruz de Bárcena is a category 2 climb that packs a genuine punch into a compact 5.7 km. From a valley floor at 67 m, the road rises to a summit of 416 m, delivering 349 m of net elevation gain. The average gradient sits at a serious 6.14%, and while that number alone signals a hard effort, what makes this climb interesting is how consistent it is: with a maximum pitch of just 7.93%, there are no brutal ramps to blow you apart, but equally there is no true respite. It is a steady, grinding test of sustained power rather than explosive punch.

How the Gradient Unfolds

The story of Bárcena is one of relentlessness. The gap between the 6.14% average and the 7.93% maximum is narrow — under two percentage points — which tells you almost the entire climb hovers close to that average. There are no flat sections to spin the legs out, and no long descents hiding in the profile that would inflate the total ascent. In fact, the total ascent of 327 m is a touch below the 349 m net gain, confirming the road climbs almost continuously without giving anything back. Expect the steepest sections near 7.93% to arrive in the middle third, where the road tilts up just enough to force a gear change, before settling back toward the average as you approach the 416 m summit.

Pacing Notes

This is a climb best ridden by the numbers rather than by feel. Because the gradient never spikes wildly, you can hold a remarkably even effort from bottom to top — ideally pinned just below or right around your threshold. Aim to ride the whole 5.7 km at a percentage of your FTP you can sustain for the full duration; going deep into the red early has no payoff on a climb this uniform. If you do not know your threshold, run the FTP estimator first and set a target power before you start. The temptation on the middle ramps near 7.93% is to surge — resist it, and let the steady 6.14% average do the work of setting your rhythm.

Gearing

For most riders a compact chainring paired with a wide cassette is ideal here. A 34×32 will comfortably carry strong climbers through the 7.93% pitches while keeping cadence high on the sustained 6.14% average. If you are carrying fatigue, riding at a heavier build, or simply prefer to spin, step up to a 34×34 — the extra sprocket takes the sting out of the steepest middle section and lets you protect your legs across the full 349 m of gain. Neither the length nor the maximum gradient demands anything more exotic than that.

Summary

La Cruz de Bárcena rewards discipline over drama: a uniform, honest category 2 climb where even pacing and sensible gearing matter far more than raw punch. Ride it smooth and you will crest the 416 m summit with power to spare.
