Alto de la Planchada

Alto de la Planchada cycling climb profile

Alto de la Planchada is a long Category 2 climb in CL that asks for discipline more than aggression. The headline numbers are clear: 20.1 km at an average gradient of 4.31%, starting at 593 m and topping out at 1458 m. That gives the climb a net elevation gain of 865 m, which is enough vertical to make poor pacing show up well before the summit.

The key detail is the spread between the average gradient and the maximum gradient. A 4.31% average over 20.1 km suggests a climb that is often rideable in rhythm, but the 11.26% maximum gradient changes the way it should be approached. This is not a pure diesel climb where one gear and one power target will carry you from bottom to top. The average tells you the climb has plenty of manageable terrain; the maximum tells you there are sharper ramps that can pull riders above threshold if they arrive overgeared or already too close to the limit.

How the gradient shapes the ride

With the available profile data, the safest way to read Alto de la Planchada is as a long, moderate climb punctuated by harder moments rather than a sustained wall. Because the average is well below the maximum, the gradient is not uniform from bottom to summit. That matters tactically. The easier sections are not invitations to surge; they are where you should reset cadence, lower muscular tension, and keep the effort anchored.

From 593 m to 1458 m, the climb gains enough height that the final portion will punish early enthusiasm. Even if the road feels controlled at the bottom, 20.1 km is long enough for small pacing errors to compound. The most efficient ride is likely a steady aerobic effort with short, controlled allowances for the steepest ramps, rather than trying to flatten the climb with repeated accelerations.

Pacing and gearing notes

Aim to start below your sustainable climbing effort, especially if riding by /glossary/ftp. On a climb this long, the correct opening should feel almost too calm. If you are already pressing hard in the first part, the 11.26% sections will force a costly spike later.

Gearing should be chosen for the steepest ramps, not the average. The 4.31% average can make the climb look deceptively forgiving on paper, but a maximum gradient above 11% means low gearing is useful for keeping cadence under control when the road kicks up. If you have to grind those ramps, the metabolic cost rises quickly and recovery on the gentler sections becomes less effective.

For training, Alto de la Planchada is well suited to long tempo or sweet spot work with strict control over surges. The best execution is simple: ride the moderate gradients smoothly, cap the spikes on the steepest pitches, and save enough to keep form intact all the way to the 1458 m summit.
