Alto de la Mera

Alto de la Mera cycling climb profile

Alto de la Mera is a short, controlled category 4 climb in CL: 2.4 km from 222 m to 371 m, with 149 m of net elevation gain. The headline number is the 6.33% average gradient, but the more useful detail is how close the maximum gradient is to that average. With a listed max of 7.06%, this is not a climb defined by a single wall or a brutal final ramp. It is a climb where the effort is likely decided by how cleanly you settle into rhythm.

That matters tactically. On a climb this short, the temptation is to ride it like an extended surge, especially because the gradient never reads as extreme. But 2.4 km at this grade is long enough for early over-pacing to show up before the summit. The correct approach is not defensive, but it should be disciplined: get on top of the gear quickly, keep the cadence from bogging down, and avoid the kind of acceleration that pushes you above sustainable power before the climb has properly started.

Gradient and effort

The available profile gives a simple message: steady pressure. An average of 6.33% with a 7.06% maximum suggests the climb should be ridden as one continuous load rather than broken into survival sections. There is no statistical evidence here for a sharp easing or a violent pitch, so the safest pacing model is a smooth build from bottom to summit.

For riders using power, this is a classic short-climb pacing problem. If the target is a hard but controlled effort, start just under your intended ceiling for the opening section, then let the effort rise once breathing and cadence are stable. Riders working from /glossary/ftp should be careful not to confuse the climb’s modest category with an easy effort. A category 4 climb can still bite if ridden above threshold too early.

Gearing notes

Because the maximum gradient is listed at 7.06%, Alto de la Mera does not demand ultra-low bailout gearing in normal conditions. The better setup is one that lets you hold a natural climbing cadence at around a 6% to 7% grade without grinding. If you need to stand, it should be to reset momentum or change muscle load, not because the gear has run out.

The cleanest ride is likely seated, measured, and slightly progressive. Treat the first half as the setup, not the attack. If there is a move to make, the numbers point toward making it late, when the short length limits the time you have to pay for going over the limit.
