Paso de Puquintica

Paso de Puquintica cycling climb profile

Paso de Puquintica is not a climb defined by brutal gradients. On paper, it is a compact category 4 ascent in Chile, running 3.2 km at an average gradient of 3.43%. The road rises from 4,068 m to 4,178 m, gaining 110 m between start and summit.

That combination matters. The gradient is modest, but the elevation is not. This is the type of climb where the numbers can tempt a rider into treating it like a false flat, only for the effort to feel heavier than expected once the oxygen cost catches up. The maximum gradient is 4.86%, so there is no single wall that should decide the climb. The limiter is more likely to be pacing discipline than raw strength.

How the gradient unfolds

With an average of 3.43% across 3.2 km and a maximum of 4.86%, Paso de Puquintica should ride as a steady, rolling drag rather than a climb with sharp changes in rhythm. The key point is that the ceiling is not much higher than the average, which suggests the road does not force repeated accelerations or big gear changes.

That makes it tactically simple but physiologically easy to misjudge. A rider can stay seated, hold momentum, and keep pressure on the pedals without needing to surge. The danger is drifting too far above a sustainable effort early because the slope never looks intimidating. At this elevation, that mistake is harder to correct than it would be lower down.

Pacing and gearing notes

Treat the lower section as a controlled entry, not a launchpad. The climb is short enough that a strong rider may want to press from the bottom, but the altitude argues for a smoother approach. Build the effort gradually, settle into a rhythm, and only tighten the pace once the summit is clearly within reach.

Gearing should be chosen for cadence stability rather than survival. The maximum gradient of 4.86% does not demand extreme climbing gears, but a slightly easier ratio than usual can help avoid grinding if breathing becomes the limiter. This is a climb where staying aerobic and efficient matters more than forcing a big gear.

For riders using power, anchor the effort to your tested /glossary/ftp rather than the way the gradient looks. Paso de Puquintica is gentle enough to invite overpacing, but high enough that a small excess effort can have an outsized cost. The fastest ride here is likely the one that feels almost too controlled at the bottom and still has pressure at the top.
