Fuorcla Grevasalvas cycling climb profile

Fuorcla Grevasalvas is a long Swiss category 1 climb that asks for patience more than bravado. On paper, 17.8 km at 5.12% looks manageable, but that average hides the real pacing problem: the road gains 911 m from a start elevation of 1115 m to a summit elevation of 2026 m, while the maximum gradient reaches 12.5%.

That combination tells you the climb is not just a steady tempo drag. A 5.12% average over this distance gives enough room for recoverable sections, but the 12.5% maximum means there are ramps steep enough to punish anyone riding too close to threshold early. The listed total ascent is 903 m, so the work is concentrated and sustained rather than a rolling approach with large descents breaking it up.

How the gradient unfolds

The available profile does not place the steepest ramps at a specific point, so the smart way to ride Fuorcla Grevasalvas is to treat the whole climb as variable until proven otherwise. From the bottom, the opening kilometres should feel deliberately restrained. The climb starts high enough that the effort can feel a little less forgiving than the gradient suggests, and the full 17.8 km distance means early surges have a long time to compound.

Through the middle of the climb, the average gradient is the useful anchor. If the road is sitting near that 5.12% feel, stay smooth and avoid chasing speed. If it kicks up, the 12.5% maximum should be your warning not to fight the bike in a big gear. The danger is not one steep pitch by itself, but the repeated cost of lifting power well above sustainable climbing effort.

Near the summit, the numbers argue for keeping something in reserve. A climb finishing at 2026 m after 911 m of vertical gain is long enough that pacing errors made low down will show up late. If you still have control over cadence and breathing in the final section, you have probably ridden it correctly.

Pacing and gearing notes

Ride this as a controlled endurance-to-threshold climb, not as a short maximal effort. Use /glossary/ftp as the ceiling for decision-making rather than the target from the base. The right effort is one that lets you absorb the steepest ramps without repeatedly going deep into the red.

Practical approach:

• Start below your intended climbing effort for the first phase.
• Shift early on steeper pitches and protect cadence before the gradient bites.
• Avoid standing accelerations unless they are used to relieve pressure, not to increase speed.
• Save your hardest sustained effort for the final part of the ascent.

Gearing should account for the 12.5% maximum, not just the 5.12% average. If your setup is only comfortable on moderate gradients, the steepest sections will force low-cadence torque spikes. That is costly on a climb this long. A compact-friendly climbing gear, or any ratio that lets you stay seated and fluid on double-digit gradients, is the safer choice.

Bottom line

Fuorcla Grevasalvas rewards riders who respect the distance. The headline average is approachable, but the length, the 911 m rise, and the 12.5% maximum gradient make it a climb where discipline matters. Keep the early effort quiet, gear for the ramps, and let the final kilometres decide how hard you can really ride.
