Paso de la Punilla

Paso de la Punilla cycling climb profile

Paso de la Punilla is a Category 1 climb in AR, and its difficulty is built less around savage ramps than sustained accumulation. The headline numbers tell the story clearly: 41.1 km in length, an average gradient of 4.07%, a maximum gradient of 5.7%, and a rise from 1645 m to 3318 m. The net elevation gain is 1673 m, with total ascent listed at 1662 m.

That profile points to a climb where the limiter is pacing discipline. A 4.07% average gradient over 41.1 km rarely feels brutal in the opening phase, but that is exactly the trap. The gradient is shallow enough to invite bigger gears and higher speed, yet long enough that repeated small over-threshold efforts will compound. If you ride it like a short climb, it will punish you late.

How the gradient unfolds

With a maximum gradient of 5.7%, Paso de la Punilla appears to be relatively controlled in its steepness. The gap between the average gradient and the maximum gradient is not large, which suggests the climb is more of a prolonged drag than a staircase of violent pitches.

That matters tactically. On climbs with sharper ramps, pacing is often dictated by survival through the steepest sections. Here, the decision-making is subtler. Because the road does not appear to force huge changes in effort, the rider has to impose structure from the bottom rather than waiting for the terrain to do it.

The practical sensation should be a long aerobic grind: enough gradient to keep pressure on the pedals, but not so steep that momentum disappears. This makes it easy to drift above sustainable power without noticing, especially if there is a tailwind, group momentum, or a section that feels deceptively fast.

Pacing and gearing notes

The best approach is controlled and conservative early. Treat the lower slopes as a setup phase, not a place to prove form. On a climb this long, the cost of riding slightly too hard early is much higher than the benefit of gaining a small amount of time.

Use a gear that lets you keep smooth torque rather than forcing a low-cadence grind. Since the maximum gradient is 5.7%, most riders will not need emergency climbing gears, but a compact or wide-range setup still makes sense because fatigue, not steepness, is the main threat. The right gear is the one that keeps effort stable when the climb feels too easy to respect.

If riding by power, anchor the effort around sustainable climbing intensity rather than chasing speed. A climb at 4.07% can make speed fluctuate enough that perceived progress becomes misleading. Use /glossary/ftp as the reference point for pacing, and resist the temptation to lift every time the road feels manageable.

The final takeaway is simple: Paso de la Punilla is not defined by one decisive ramp. It is defined by whether you can hold an efficient, repeatable effort for 41.1 km while climbing to 3318 m. The riders who finish strongest will usually be the ones who made the least dramatic choices early.
