Alto de Morro

Alto de Morro cycling climb profile

Alto de Morro is a compact but demanding Colombian Category 1 climb. On paper, the key number is not the 5.5 km length. It is the 10.65% average gradient. That combination changes the ride completely. This is not a climb where the first half can be floated through before the race starts later. The gradient is already severe enough that every acceleration has a cost, and that cost arrives quickly.

The road starts at 711 m and reaches 1292 m, with 581 m of net elevation gain. Across only 5.5 km, that tells you the defining feature: there is very little cheap vertical gain here. Even if the road briefly eases, the overall profile means the climb has to keep coming back at you. The listed maximum gradient of 18.81% is the number that should shape how you pace the entire ascent, because steep ramps like that punish riders who arrive over-geared or already above threshold.

How the gradient rides

The available profile does not break Alto de Morro into named sections, so the honest way to read it is through the relationship between its average and maximum gradient. A 10.65% average means the climb is consistently hard. The 18.81% maximum means the hard baseline is interrupted by very steep pitches, not just a steady tempo road.

That matters tactically. On a climb averaging this much, a rider who tries to ride by speed will almost always go too deep. Speed will fluctuate sharply with gradient, and trying to hold it steady on the steepest ramps will push power well above sustainable range. The better approach is to let speed fall when the road kicks up and protect cadence as much as possible.

Pacing and gearing notes

Start below your target climbing effort, not at it. On a short climb, the temptation is to treat the opening as a launchpad, but the average gradient leaves little margin for recovery. If you go over your sustainable power early, the upper part of the climb becomes damage limitation.

Use your easiest climbing gear before you need it. The 18.81% maximum gradient is steep enough that shifting late can force a low-cadence grind, especially if the surface or traction is imperfect. A compact climbing setup, or at minimum a gear that lets you stay seated on double-digit gradients, is the right tool for this climb.

For riders pacing from /glossary/ftp, the cleanest strategy is controlled pressure for the opening, restraint on any early ramp, then a progressive lift only once the summit effort is clearly manageable. Alto de Morro rewards torque resistance, but it rewards discipline more. The rider who keeps the steepest ramps under control will usually climb faster than the rider who attacks them and spends the final section trying to recover.
