Paso de Icalma

Paso de Icalma cycling climb profile

Paso de Icalma is a short, contained climbing effort rather than a long mountain grind. The numbers define the experience clearly: 2.2 km at an average gradient of 6.15%, starting at 1168 m and topping out at 1304 m. With 136 m of net elevation gain and a listed maximum gradient of 8.8%, it is enough to force a real climbing rhythm, but not long enough to reward hesitation.

Its Category 4 rating fits the profile. This is not a climb where endurance decay becomes the main limiter. The key is managing the first minutes well enough that the steeper sections near the 8.8% ceiling do not push you above a sustainable effort too early.

How the gradient rides

The average gradient of 6.15% suggests a climb that is consistently uphill rather than brutally irregular. But the maximum gradient of 8.8% matters because, on a climb this short, even a brief steepening can dominate the pacing if you attack it in the wrong gear.

Think of Paso de Icalma as a controlled threshold-to-over-threshold effort. The climb is long enough that a sprint from the bottom is inefficient, but short enough that riding too conservatively leaves time on the road. The practical target is to settle quickly into a firm rhythm, keep the power smooth through the middle, then allow the effort to lift once the summit is clearly within reach.

Because the elevation gain is compact, speed changes will be driven more by gradient shifts than fatigue accumulation. If the road pitches toward the maximum gradient, cadence will naturally fall unless you shift early. Waiting until the slope bites is the mistake - it turns a manageable ramp into a torque-heavy grind.

Pacing and gearing notes

For pacing, avoid treating the opening like a free section. On a 2.2 km climb, early over-pacing has an immediate cost because there is not enough distance to fully recover before the upper part. Start just under the effort you want to hold, then build once breathing and cadence have stabilized.

A few practical cues:

• Shift before the steepest ramps rather than after cadence drops.
• Stay seated through most of the climb unless the gradient approaches the 8.8% maximum and you need to reset momentum.
• Use a gear that lets you keep pressure on the pedals without grinding.
• If pacing by /glossary/ftp, this is the kind of climb where a controlled effort slightly above steady endurance climbing can work, provided the final steepest section is not reached already in the red.

Bottom line

Paso de Icalma is short, moderate, and tactically simple, but that does not mean it is effortless. Its 6.15% average gradient makes it rideable at a steady tempo, while the 8.8% maximum gradient punishes sloppy gear choice. The fastest ride comes from restraint at the base, clean shifting through the steeper moments, and a committed finish over the final stretch to 1304 m.
