Paso de la Laguna del Pelado

Paso de la Laguna del Pelado cycling climb profile

Paso de la Laguna del Pelado is not defined by one violent wall. It is defined by the cost of staying on the pedals for 49 km while climbing from 812 m to 3274 m. That gives it a net elevation gain of 2462 m, with 2475 m of total ascent, which tells you the key thing about the road: this is a climb that trends upward almost all the way rather than giving back large chunks of elevation.

The average gradient of 5.02% can look manageable in isolation, but on a climb of this length it becomes a pacing problem more than a pure strength problem. The road asks for sustained aerobic discipline. If you ride the lower slopes as if the average gradient is the whole story, the upper half becomes expensive quickly, because the climb still has enough bite to reach a maximum gradient of 11.92%.

How the gradient unfolds

With the available profile data, the best way to understand the climb is as a long, mostly persistent ascent with sharper ramps embedded inside it. The small gap between net elevation gain and total ascent means there is very little meaningful descending to reset the legs. Any easing in gradient should be treated as a chance to recover while still moving, not as a reason to push harder.

That maximum gradient of 11.92% matters because it changes how the 5.02% average should be interpreted. This is not a steady trainer effort where one gear and one power target solve the day. The climb will reward riders who can keep pressure on the pedals through the moderate sections, then absorb the steeper pitches without spiking too far above sustainable output.

Pacing and gearing notes

Start conservatively. For most riders, the correct first move is to keep the early effort below /glossary/ftp rather than trying to bank time. On a 49 km HC climb, small overextensions compound. The goal is to arrive deep into the climb still able to choose your cadence, not forced into survival mode.

Gear for the maximum gradient, not the average. A 5.02% average might tempt a rider into a tighter setup, but the 11.92% ramps demand a low enough gear to stay seated and controlled when fatigue is already present. If the cadence collapses on those ramps, the climb becomes muscular rather than aerobic, and that is usually where pacing mistakes show up.

The cleanest strategy is simple: ride the long middle of the climb at a repeatable endurance-to-tempo effort, use any gentler sections to lower breathing and reset posture, and keep the steepest ramps smooth rather than heroic. Paso de la Laguna del Pelado is an HC climb because the total workload is enormous. Respect the duration first, then manage the gradient.
