La Stretta

La Stretta cycling climb profile

La Stretta is a category 1 climb in Switzerland built around sustained accumulation rather than one simple wall. The headline numbers are clear: 31.7 km in length, 1,428 m of net elevation gain, and an average gradient of 4.51%. On paper, that average can look manageable. On the road, the length changes the equation. A climb this long rewards discipline more than aggression, because small early mistakes have a long time to compound.

The start sits at 1,016 m and the summit at 2,444 m, so this is not just a climb with a high finish. It begins already well above valley-floor elevation and keeps asking for work deep into the ascent. The total ascent is 1,651 m, which is higher than the net gain. That matters. It tells you the road is not a perfectly steady ramp from bottom to top. There is extra climbing hidden inside the profile, likely through flatter sections, interruptions, or elevation losses that force you to regain height later.

How the gradient rides

The 4.51% average should be read as the climb’s overall load, not as a promise of steady gradients. The maximum gradient is 10.62%, which means there are sections steep enough to break rhythm if you arrive overgeared or already riding too close to threshold.

That combination - long distance, moderate average, double-digit maximum - usually creates a tactical problem. If you pace only off the average, the steeper ramps will feel sharper than expected. If you pace only for the steepest section, you may ride too defensively for too long. The better approach is to treat La Stretta as a long aerobic climb with short moments that require torque control.

Pacing and gearing notes

Ride the lower slopes with restraint. The climb is too long to justify chasing speed early, especially because the total ascent figure shows there is more work than the net elevation gain alone suggests. If using power, anchor the effort below /glossary/ftp and leave room for the 10.62% maximum gradient. If riding by feel, the opening effort should feel deliberately controlled, not merely sustainable.

Gearing should be chosen for the steepest ramps, not the 4.51% average. A comfortable climbing gear matters here because the decisive cost is not one isolated pitch, but repeated force production over 31.7 km. If cadence collapses on the steepest section, the climb will start taking muscular matches that are difficult to recover on a route with this much total ascent.

The practical goal is simple: keep pressure on the pedals when the gradient is mild, avoid spikes when it steepens, and save enough margin to handle the final altitude gain to 2,444 m without turning the last part into damage control. La Stretta is not defined by a brutal average gradient. It is defined by how long it keeps asking you to climb.
