Passo della Mulattiera cycling climb profile
The Passo della Mulattiera cycling climb is not defined by one isolated wall. It is defined by how long it asks you to keep producing climbing power. At 17.2 km with an average gradient of 7.79%, this is an HC ascent where the average already tells a serious story before the maximum gradient enters the conversation.
The climb starts at 1093 m and finishes at 2436 m, gaining 1343 m from bottom to summit. That vertical scale matters because it turns the effort from a hard climb into a full pacing problem. On a shorter ascent, a rider can absorb a few over-threshold surges and recover later. Here, the distance and elevation gain make every early acceleration expensive.
How the gradient unfolds
The available profile points to a climb that is sustained rather than forgiving. An average of 7.79% across 17.2 km means there is little room to treat the opening as a warm-up or assume the middle will provide meaningful recovery. Even before the steepest section, the baseline workload is already high.
The key tactical detail is the maximum gradient of 16.62%. That is steep enough to change the ride from aerobic climbing into a torque-management problem, especially if it arrives when fatigue is already built up. Because the overall average is close to 8%, those steeper ramps are not sitting inside an easy climb. They are layered onto an already demanding ascent, which is exactly the combination that breaks pacing discipline.
In practical terms, the climb should be ridden as a long threshold-adjacent effort with protected reserves for the steepest pitches. If you chase speed too early, the 16.62% sections will force a costly spike. If you hold back too much, the length of the climb means you can still finish well by riding the final portion with control rather than survival.
Pacing and gearing notes
Gear for the maximum gradient, not the average. A setup that feels comfortable at 7.79% can become marginal when the road reaches 16.62%, particularly after sustained climbing time has already accumulated. Choose a low enough climbing gear to stay seated when possible and avoid grinding yourself into repeated high-torque efforts.
For pacing, anchor the effort to a sustainable climbing output rather than the speed on the road. This is the kind of ascent where speed will fluctuate sharply with pitch, but the physiological cost of each surge remains. If you ride with power, keep the early effort controlled relative to your /glossary/ftp and allow only short, deliberate increases on the steepest ramps.
The best approach is conservative but not passive: settle early, keep cadence from collapsing, and save the real decisions for the upper part of the climb. Passo della Mulattiera rewards riders who respect the arithmetic of the ascent - 17.2 km, 1343 m gained, and gradients steep enough to punish anyone who treats the average as the whole story.
