Paso de Álica (Agua Buena)

Paso de Álica (Agua Buena) cycling climb profile

Paso de Álica (Agua Buena) is an HC climb in Mexico that should be treated as a long, sustained threshold-management effort rather than a climb you can bluff through on freshness. The numbers are clear: 19.4 km at an average gradient of 7.56%, rising from 144 m to 1607 m, with 1463 m of net elevation gain.

That combination matters. A climb can average over 7% because it has a few brutal ramps and long recoveries, or because it keeps applying pressure with very little room to reset. With only the headline gradient data available, the safest read is the second one: this is a climb where the average itself is already hard enough to define the ride. The maximum gradient of 12.97% adds another layer, because any rider already pacing too close to the limit will feel those steeper pitches immediately.

How the gradient feels

The defining feature is not a single wall, but the accumulated cost of climbing for 19.4 km at a gradient that rarely lets a rider feel fully unloaded. An average of 7.56% over this distance means the climb demands continuous torque and aerobic control. Even if some sections ease, they should be treated as opportunities to stabilize breathing and cadence, not as invitations to surge.

The near-13% maximum is the tactical warning. On a climb this long, short steep sections have an outsized effect because they force either higher force per pedal stroke or a drop in cadence. If you arrive at those ramps already above sustainable effort, the cost compounds quickly. The climb rewards riders who keep the early effort contained and preserve enough gear range to stay seated when the road kicks up.

Pacing and gearing notes

Start conservatively. The first priority is to lock into a pace you can hold while still absorbing steeper sections without spiking far beyond your sustainable climbing power. If riding by power, this is a climb where discipline around /glossary/ftp matters more than chasing speed changes caused by gradient shifts.

Gearing should be chosen for the maximum gradient, not just the average. A setup that feels fine at 7.56% can become costly when the road touches 12.97%, especially deep into a 19.4 km ascent. Use a low gear that allows a seated cadence on the steepest pitches, because standing repeatedly to force a gear will raise muscular load and make the final part of the climb harder than it needs to be.

For stronger riders, the mistake is attacking the gradient too early. For steadier endurance riders, the risk is under-gearing and grinding. Either way, the logic is the same: Paso de Álica is long enough, steep enough, and classified hard enough that pacing errors show up before the summit, not after it.
