Paso de Mahuida

Paso de Mahuida cycling climb profile

Paso de Mahuida is the kind of climb where the numbers tell you the main tactical problem immediately. At 4.2 km, it is not long enough to settle into the slow-burn rhythm of a major pass, but an 8.66% average gradient means it is too steep to ride casually or bluff your way through on momentum. The climb starts at 116 m and tops out at 481 m, gaining 365 m from bottom to summit.

That combination makes it a compact, high-pressure effort. A rider who attacks the opening as if the distance is the defining feature will quickly find that the gradient is actually the more important variable. The maximum gradient is 13.22%, so even if the road is not described here by detailed kilometre splits, the profile clearly has sections steep enough to force a change in cadence, gear choice, or pacing.

How the gradient rides

With only 4.2 km to cover and an average of 8.66%, Paso de Mahuida offers little mathematical space for sustained recovery. The road has to stay meaningfully uphill for most of the climb to produce that average. The practical expectation should be a climb that feels consistently loaded, with harder ramps that can push into the low-teens.

The key point is that the maximum gradient is not just a headline number. On a short climb, a 13.22% ramp can do disproportionate damage because it arrives inside an effort that is already above comfortable endurance intensity. If you overgear those steeper pitches, the cost is not just local muscular fatigue - it can force you over your sustainable power and leave the final part of the climb feeling longer than the distance suggests.

Pacing and gearing notes

Treat Paso de Mahuida as a controlled threshold-style climb with short periods of extra torque when the road bites. The first priority is avoiding an early surge simply because the climb is short. Four kilometres at this gradient is still enough time for a poor opening minute to decide the ride.

Use a gear that lets you keep pressure on the pedals without grinding when the slope approaches its steepest sections. If your easiest climbing gear is already marginal on gradients above 10%, this is a climb where cadence will drop and muscular fatigue will become the limiter before breathing does.

A sensible pacing approach:

• Start deliberately, not passively, and let the gradient bring the effort up.
• Keep one gear in reserve for the steepest ramps up to 13.22%.
• Avoid standing accelerations unless they are used to reset cadence, not to attack the climb.
• Ride the final section by effort rather than speed, because the gradient is steep enough to make speed a poor guide.

For riders using power, anchor the effort around your sustainable climbing output rather than chasing a time target from the base. If you need a reference point, tie the pacing back to /glossary/ftp or estimate your current range with /tools/ftp-estimator before using this climb as a benchmark effort.

Bottom line

Paso de Mahuida is a category 2 climb that rewards discipline more than aggression. Its 4.2 km length tempts riders into going too hard too soon, while its 8.66% average and 13.22% maximum punish any mismatch between pacing and gearing. Ride it with respect from the bottom, stay light on the steepest ramps, and the summit comes from control rather than rescue pacing.
