Puerto de Timbuscatío (La Alcantarilla) cycling climb profile

Puerto de Timbuscatío (La Alcantarilla) is a short climb on paper, but the numbers make the riding problem very clear. It is 6.2 km long, starts at 651 m, tops out at 1279 m, and gains 628 m from bottom to summit. That produces an average gradient of 10.08 percent, which puts it firmly in the category of climbs where pacing discipline matters more than enthusiasm.

The key detail is the maximum gradient of 28.59 percent. A climb averaging just over 10 percent is already demanding. When the steepest pitch reaches that level, the profile is not just hard because of its length - it is hard because there are sections where momentum, gearing, and body position can become limiting factors.

How the gradient rides

With only 6.2 km to work with, Puerto de Timbuscatío does not give much room to recover from a bad opening. The average gradient tells you the road is consistently uphill enough that any early over-pacing will compound quickly. This is not the kind of climb where a rider can burn matches at the base and expect a long false flat to reset.

The maximum gradient changes the way the whole climb should be ridden. Even if that 28.59 percent section is brief, it forces a conservative approach before it arrives. On gradients that steep, seated rhythm often breaks down, cadence drops, and power can spike well above /glossary/ftp even if perceived effort feels controlled. The danger is not just the steep ramp itself, but the oxygen debt carried out of it.

From bottom to summit, think of the climb as a sustained double-digit effort with at least one severe pitch capable of deciding the ride. The summit elevation of 1279 m is not the main limiter. The gradient is.

Pacing strategy

The right approach is to start under control, even if the first slopes feel manageable. On a climb averaging 10.08 percent, riding the opening by speed is misleading because speed will be low even at a sustainable effort. Use power or perceived exertion instead.

A smart pacing plan:

• Ride the first part below threshold rather than at it
• Keep cadence high enough to avoid grinding before the steepest ramps
• Stay seated where possible to conserve traction and muscular load
• Stand only when the gradient forces it or to reset fatigue
• Save the final sustained effort until the worst ramps are behind you

If using a power target, this is a climb where normalized effort can run away from average power because of the steep surges. The goal is not to flatten every ramp with force. It is to keep the steepest section from forcing a complete reset.

Gearing notes

Choose easier gearing than the 6.2 km length might suggest. The 28.59 percent maximum gradient is the decisive number for setup. A gear that feels adequate for a 10.08 percent average may still be too heavy when the road pitches sharply upward.

For most riders, compact gearing and a wide-range cassette are the safer choice. The priority is keeping the pedals turning when the slope bites, not carrying speed. If cadence collapses on the steepest section, the climb becomes a torque test rather than an aerobic effort.

Bottom line

Puerto de Timbuscatío (La Alcantarilla) is a Category 1 climb because the difficulty is concentrated and severe. Its 6.2 km length makes it tempting to attack, but the 10.08 percent average and 28.59 percent maximum reward restraint. Ride the bottom with patience, protect your cadence, and treat the steepest ramp as the moment the climb is likely to be decided.
