Alto del Cortezo

Alto del Cortezo cycling climb profile

Alto del Cortezo is a short, controlled category 4 climb rather than a long endurance test. The numbers define the ride clearly: 2.4 km at an average gradient of 5.64%, starting at 9 m and topping out at 142 m. That gives it a punchy shape - enough elevation change to force a real effort, but not enough road to recover from a badly paced opening.

The key figure is the maximum gradient of 9.47%. On a climb this short, that matters more than the average suggests. A steady 5.64% would be manageable at a strong tempo, but a near double-digit ramp changes the pacing equation. If you ride the lower slopes too aggressively, the steepest section will push you above sustainable power before the summit.

How the gradient rides

With 133 m between the stated start and summit elevations, Alto del Cortezo feels like a compact vertical gain delivered quickly. There is no room for a long settling-in phase. The climb asks you to find rhythm almost immediately, then protect that rhythm when the road tips up toward its steepest pitch.

The supplied profile also lists total ascent at 102 m, which is lower than the 133 m difference between the stated start and summit elevations. That makes the broad profile more useful than any attempt to over-read micro-variations. The practical takeaway is simple: this is a short climb with a moderate average, but the steepest ramp is sharp enough to punish overgearing.

Pacing and gearing notes

Treat the first part as a setup, not a launch. On a 2.4 km climb, it is tempting to ride hard from the base, especially because the average gradient looks manageable. That is usually the wrong move. Keep the effort just under control early, then let the pace rise once you know where the 9.47% section sits under your legs.

Gearing should be light enough that you can stay seated and keep cadence from collapsing on the steepest ramp. If you are forced into a low-cadence grind before the summit, you have either chosen too hard a gear or burned too much above /glossary/ftp too early.

For training, Alto del Cortezo suits short threshold work, over-under efforts, or repeated climbing intervals. For a timed attempt, the fastest ride will usually come from restraint at the bottom, efficient gear changes through the steepest pitch, and a final acceleration only once the summit is close enough to commit.
