Paso de la Yerbabuena

Paso de la Yerbabuena cycling climb profile

Paso de la Yerbabuena is a category 2 climb in MX that asks for patience more than brute force. The profile is 12.1 km long, rises from 1536 m to 2048 m, and gains 512 m in total. With an average gradient of 4.23% and a maximum gradient of 7.46%, this is not defined by extreme steepness. It is defined by the duration of the effort and the need to keep pressure on the pedals without drifting above a sustainable ceiling.

The useful clue in the supplied profile is that the net elevation gain and total ascent are both 512 m. That means the climb, as represented here, does not give away meaningful height through descents. You should treat it as a steady uphill problem: once the road starts rising, the work continues all the way to the summit.

How the gradient rides

The average gradient of 4.23% puts Paso de la Yerbabuena in the controlled, aerobic climbing range for a trained rider. It is steep enough that drafting and momentum matter less than on rolling terrain, but not so steep that cadence is forced down by the slope alone. The maximum gradient of 7.46% suggests there are sharper ramps, but the data does not support treating the climb as a series of severe walls.

That distinction matters tactically. A climb like this rewards riders who avoid overreacting to each pitch. The hardest sections are likely to feel noticeably slower, but the ceiling is still within a range where pacing discipline can prevent major damage. The risk is not one single brutal ramp. The risk is riding the early moderate gradient as if it is free, then finding that the final portion feels much longer than the numbers suggested.

Pacing strategy

Start below the effort you think you can hold. On a 12.1 km climb, the first mistake is usually not visible on the first steep pitch. It shows up later, when the same 4.23% average starts to feel inefficient because cadence has fallen and breathing is no longer controlled.

If riding by power, anchor the climb around a sustainable threshold-adjacent effort rather than chasing every gradient change. Use /glossary/ftp as the reference point, but keep enough margin for the 7.46% maximum ramps. If riding by feel, the right opening effort should feel productive but slightly restrained: firm pressure, stable breathing, and no need to surge out of the saddle unless the road briefly asks for it.

Gearing notes

Because the maximum gradient is 7.46%, Paso de la Yerbabuena does not require ultra-low mountain gearing for most fit riders, but it does reward having one or two easier gears in reserve. The goal is to keep cadence smooth when the road tips up rather than grinding through the steeper moments and paying for it across the remaining distance.

A compact or climbing-friendly setup gives more tactical room here. The climb is long enough that saving muscular fatigue is worth more than proving you can push a bigger gear. Choose the gear that lets you stay seated, keep pressure even, and ride the gradient as one continuous effort from 1536 m to 2048 m.
