Alto de Las Catalinas

Alto de Las Catalinas cycling climb profile

Alto de Las Catalinas is short enough to look manageable on paper, but the numbers say something very different. At 1.4 km with an average gradient of 15.4%, this is not a climb you settle into in the usual aerobic sense. It is a compact, high-torque effort where the cost of going even slightly too hard early is paid almost immediately.

The climb starts at 24 m and rises to 236 m, with a net elevation gain of 212 m. That means the road gets to work quickly. There is no statistical suggestion here of a long approach, a gentle preamble, or a climb that builds slowly toward the summit. The defining feature is steepness from bottom to top.

How the gradient rides

The key detail is the relationship between the average gradient and the maximum gradient. An average of 15.4% and a maximum of 16.98% points to a climb where the hardest ramps are not wildly detached from the general character of the road. In practical terms, the difficulty is not one isolated wall. The climb itself is the wall.

That makes pacing less about waiting for a known decisive section and more about controlling torque from the first metres. On a longer climb, a rider can often recover from an over-ambitious opening by easing into steadier terrain. Here, the short length and severe average gradient reduce that margin. If you spike the effort early, there is not enough distance left for the physiology to reset before the summit.

Pacing and gearing notes

Treat Alto de Las Catalinas as a seated strength effort with the option to stand only when cadence starts to collapse. The best pacing strategy is conservative at the base, controlled through the middle, then full commitment only once the summit is clearly within reach.

Gearing matters more than speed here. Choose the easiest climbing gear available before the slope forces the decision for you. On gradients this steep, shifting under heavy load can be inefficient and risky, so arrive at the base already in a gear that lets you keep pressure smooth rather than wrestling the bike.

For riders using /glossary/ftp as a pacing anchor, this is likely to feel closer to a hard anaerobic-climbing effort than a steady threshold climb, despite the short distance. The limiter will be muscular force, traction, and the ability to keep the front end settled while maintaining forward momentum.

Bottom line

Alto de Las Catalinas is a compact category 2 climb in Chile, but its difficulty is concentrated. At 1.4 km and 15.4%, it rewards restraint, low gearing, and a clean seated rhythm. The rider who wins this climb is not the one who attacks the bottom hardest, but the one who still has control when the gradient refuses to ease.
