Paso de Lislique

Paso de Lislique cycling climb profile

Paso de Lislique is a compact but demanding climb: 3.6 km at an average gradient of 9.92%, rising from 394 m to 751 m for 357 m of net elevation gain. On paper, the defining feature is not the length. It is the density of the climbing. When a climb averages just under 10% for this distance, there is very little room to hide from the gradient.

This is why the climb deserves respect despite its short profile. A category 2 ascent of 3.6 km does not usually become decisive through duration alone. It becomes decisive because the effort sits close to the point where riders are forced out of rhythm: too steep to comfortably spin for long, too long to treat as a simple seated punch.

How the gradient unfolds

The available profile data does not give separate kilometre-by-kilometre splits, so the smart read is based on the full-climb numbers. An average of 9.92% across 3.6 km means the road is consistently serious from bottom to summit. Even if there are small changes in pitch, the overall demand is steady enough that overpacing early will be punished quickly.

The maximum gradient of 14.79% matters because it tells you the climb includes at least one section that moves from hard tempo into torque-heavy climbing. That is the section where riders who started too aggressively will pay. At nearly 15%, cadence drops, seated power becomes harder to control, and standing efforts can spike the heart rate if they are used reactively rather than planned.

The summit at 751 m comes after a relatively direct gain from the 394 m start, so mentally this is a climb to break into effort phases rather than landmarks. The lower part should be controlled, the middle should be about holding form, and the final portion should be where any remaining power is spent.

Pacing and gearing notes

Treat Paso de Lislique as a sustained threshold-to-over-threshold climb, not a short sprint. The trap is attacking the average gradient too early. A 9.92% average already asks for a hard effort, so the pacing target should be slightly conservative at the base, especially if the climb appears in a longer ride or race.

Practical approach:

• Start one gear easier than instinct suggests, then settle into pressure rather than force.
• Keep cadence protected before the steepest ramps, because the 14.79% maximum will require spare torque.
• Avoid repeated accelerations unless the summit is close. On this gradient, each surge has a real physiological cost.
• If pacing by power, anchor the effort around your sustainable climbing output rather than chasing speed. Use /glossary/ftp as the reference point, not the gradient alone.

A compact climbing setup is the safer choice here. The climb is short enough that strong riders may be tempted to muscle through it, but the combination of length, average gradient, and maximum pitch rewards controlled gearing. If your gearing forces low-cadence grinding before the steepest section, you are already spending matches you may need near the top.

For riders estimating the required effort, /tools/ftp-estimator can help frame the climb in terms of sustainable power. The key is simple: ride the first part like the gradient will stay hard, because the overall numbers say it probably will.
