Alto de La Laguna

Alto de La Laguna cycling climb profile

Alto de La Laguna is an HC climb in Peru, and the numbers explain why. It runs for 14.2 km at an average gradient of 8.13%, starting at 1,072 m and topping out at 2,227 m. The net elevation gain is 1,155 m, which puts this firmly in the category of climbs where the main difficulty is not one isolated ramp, but the cost of holding climbing power for a long time.

The key detail is the relationship between the average gradient and the maximum gradient. With a max of 11.02%, the climb does not appear, from the available data, to be defined by extreme walls or violent gradient changes. Instead, the average sits close enough to the maximum that the practical read is simple: Alto de La Laguna is likely to feel persistently steep rather than sporadically brutal.

How the gradient unfolds

The available profile data does not break the climb into named lower, middle, and upper sectors, so the safest way to pace it is to treat the entire 14.2 km as a sustained threshold-adjacent effort with limited recovery. From the base elevation of 1,072 m, the road gains steadily toward the 2,227 m summit, and the 8.13% average means any early overreach will compound quickly.

That matters because an 8% climb of this length tends to punish riders who pace it like a shorter hill. Even if the steepest pitch only reaches 11.02%, that is still enough to force torque spikes if you arrive under-geared or already above target power. The climb asks for discipline before it asks for aggression.

Pacing and gearing notes

Start below the effort you think you can hold. On an HC climb with 1,155 m of net elevation gain, the goal is not to win the first few minutes. It is to keep the final part from becoming a survival ride. If you are pacing by power, anchor the opening effort to a sustainable number relative to your /glossary/ftp, then only lift once the summit is realistically within reach.

Gearing should be chosen for cadence control, not pride. An average gradient of 8.13% with ramps up to 11.02% means many riders will want a compact or sub-compact setup paired with a wide-range cassette. The important point is having a bailout gear that lets you stay seated and smooth when the road tips toward the maximum gradient.

For riders using this climb as a benchmark, it is a strong test of muscular endurance. If your pacing fades badly, the issue is probably not just fitness - it may be gearing, cadence discipline, or an overly ambitious start. Use a realistic power target, check it against /tools/ftp-estimator if needed, and ride the first half like the second half matters.
