Alto de Palermo

Alto de Palermo cycling climb profile

Alto de Palermo is a category 1 climb in CO, and the headline numbers explain why it deserves that classification. It runs for 17.9 km, starts at 233 m, and tops out at 1349 m, with a listed net elevation gain of 1116 m. The average gradient is 6.24%, which puts it in the range where the main limiter is not one violent ramp, but the ability to keep producing controlled power for a long time.

The important detail is the maximum gradient: 21.15%. That number changes how the climb should be read. A climb averaging 6.24% over 17.9 km could sound relatively manageable if it were perfectly even. Alto de Palermo is not a profile to treat that way. The max gradient tells you there are much sharper sections hidden inside the average, and those ramps can punish anyone riding too close to the limit early.

How the gradient unfolds

From bottom to summit, the profile is best understood as a long sustained ascent with at least one very steep pitch. The climb rises from 233 m to 1349 m, so there is no getting around the cumulative workload. Even if the road feels controlled for periods, the vertical gain keeps adding up, and the 21.15% maximum means the hardest moments are likely to require a different effort from the general rhythm of the climb.

The average gradient is useful for setting expectations, but it can also be misleading. At 6.24%, the climb invites a steady tempo approach. The problem is that any section near the maximum gradient will demand a surge in torque and breathing rate, especially if reached after a long period of climbing. That is the central tactical problem here: ride the average too aggressively, and the steepest ramps become expensive.

Pacing and gearing notes

The practical approach is conservative early, disciplined through the middle, and flexible when the road kicks up. On a 17.9 km climb, small pacing errors compound. Riding above threshold too often before the steep ramps will make the final part feel much harder than the average gradient suggests.

Gearing should be chosen for the 21.15% maximum, not the 6.24% average. A setup that feels efficient on the steadier parts may become a liability on the steepest pitch if it forces low cadence and excessive torque. For riders pacing by power, the target should sit below the level they would use for a short climb, with room to absorb the steepest sections without turning them into full anaerobic efforts. If you use /glossary/ftp as a guide, this is the kind of climb where patience usually beats ambition.

One note on the source data: the profile lists 1116 m of net elevation gain and 1097 m of total ascent. Those figures do not align if interpreted strictly, so the more useful takeaway is the broad demand: a long category 1 ascent, finishing much higher than it starts, with gradients steep enough to make gearing and pacing decisive.
