Crête Sèche

Crête Sèche cycling climb profile

Crête Sèche is a Swiss category 2 climb that asks for patience more than violence. On paper, the numbers point to a long, controlled effort: 26.4 km from 511 m to 1460 m, with 949 m of net elevation gain and a 3.6% average gradient. That average is the key to reading the climb, but it is also the number most likely to mislead a rider.

A 3.6% average across 26.4 km does not describe a consistently easy road. The maximum gradient reaches 8.59%, which means the climbing is spread unevenly. The profile is not defined by one brutal wall, but by the contrast between long moderate sections and ramps steep enough to force a change in cadence, torque, and pacing discipline.

How the gradient unfolds

From bottom to summit, the main story is duration. Starting at 511 m and finishing at 1460 m, the climb gains enough elevation to become a real aerobic load, even though the average gradient stays modest. The lower average suggests there are easier sections or flatter portions mixed into the route, while the 8.59% maximum confirms that the climb still has bite.

That combination matters tactically. On a climb like this, riders often make the mistake of treating the early gentler gradients as free speed. The problem is that the climb is long enough for those early accelerations to show up later, especially when the road pitches closer to its steepest ramps. The correct reading is not 'easy climb'. It is 'long climb with recoverable terrain and intermittent pressure points'.

Pacing strategy

The best approach is to ride the average gradient conservatively but respect the maximum gradient. Keep the opening controlled, especially if the road feels fast. With 26.4 km to cover, the cost of going slightly over target early is higher than the benefit of arriving a few seconds sooner at the next easier section.

Use the flatter or lower-gradient portions to settle breathing and reset cadence rather than to surge. When the gradient rises toward the steeper ramps, stay seated if possible and let the effort lift smoothly. This is a climb where a steady /glossary/ftp-based effort makes more sense than repeated attacks, unless the objective is race-specific intensity rather than the fastest sustainable ascent.

Gearing notes

Do not gear for the 3.6% average alone. Gear for the fact that, after a long accumulation of climbing, the road can still reach 8.59%. A comfortable climbing gear is useful even if much of the ascent feels manageable, because the steepest sections will arrive with fatigue already in the legs.

The practical setup is simple: choose gearing that lets you keep a controlled seated cadence on the steepest ramps, while still allowing efficient pedalling on the gentler stretches. If you are forced into a low-cadence grind every time the road bites, the climb will become more muscular than aerobic, which is exactly how a moderate average gradient turns into a hard day.
