Paso de Pulul

Paso de Pulul cycling climb profile

Paso de Pulul is a Category 3 climb in Argentina that looks manageable on headline numbers, but the average gradient does not tell the whole story. The climb runs for 12.5 km, rises from 962 m to 1415 m, and gains 453 m from bottom to summit. That gives it an average gradient of 3.64%, which suggests a climb that can be ridden with control rather than survived.

The key detail is the maximum gradient of 13.37%. A climb with a modest average and a steep maximum is rarely a pure metronomic effort. The numbers point to a road where easier gradients, false-flat sections, or brief recoveries offset sharper ramps. That changes the pacing problem. This is not simply a steady seated threshold climb where the best tactic is to lock into one power and wait. It is a climb where the rider who responds too hard to the steepest sections can spend energy inefficiently long before the summit.

How the gradient shapes the ride

The 3.64% average means much of Paso de Pulul should feel rideable in endurance or tempo range for a trained cyclist. But the 13.37% maximum means gearing and pacing need to be chosen for the hardest ramps, not the average slope.

That difference matters because steep ramps punish momentum loss. If you arrive overgeared, the climb can quickly force low cadence, high torque pedaling. That is costly, especially on a longer 12.5 km ascent where the total duration is long enough for small pacing mistakes to compound.

Pacing strategy

Treat the opening of Paso de Pulul as a control phase. The climb is long enough that riding above sustainable effort early has little upside, especially when the steepest gradients can appear later or after a short recovery. Use the easier sections to stay smooth rather than to chase speed.

A practical approach:

• Ride the lower-gradient sections below your limit, not at it
• Shift early before the steep ramps so cadence does not collapse
• Let power rise briefly on the 13.37% sections, but avoid turning every ramp into a maximal effort
• Use any gentler terrain to settle breathing and reset cadence

If you pace by power, this is a climb where /glossary/ftp discipline matters. The average gradient may tempt you into riding aggressively, but the ramps require a reserve. If you pace by feel, keep the effort aerobic and controlled until the summit feels clearly within reach.

Gearing notes

Do not gear Paso de Pulul as a 3.64% climb. Gear it for the steepest moments. A compact or climbing-friendly setup makes sense because the maximum gradient is severe enough to demand a bailout gear, particularly if the road surface, wind, or fatigue adds resistance.

The best ride here is not the rider who attacks every rise. It is the rider who understands that the average gradient is hiding variability, keeps torque under control, and reaches the upper slopes with enough cadence and composure to finish strongly.
