Passo di Pietra Spada cycling climb profile
Passo di Pietra Spada is a category 1 climb in Italy that asks a very specific question: can you manage a long, controlled effort without letting the easier gradients trick you into riding above target?
The climb runs for 26.5 km from 115 m to 1337 m, with 1222 m of net elevation gain. Its average gradient is 4.62%, which makes it look manageable on paper, but that figure is spread over a long distance. The difficulty is not a single wall-like section. It is the accumulation of work, the slow rise in fatigue, and the need to keep something available for the steeper ramps that reach 10.73%.
How the gradient rides
The available profile data points to a climb defined by length rather than relentless steepness. A 4.62% average over 26.5 km suggests long stretches where rhythm matters more than brute force. You should expect the climb to reward riders who can sit close to a sustainable aerobic effort and avoid repeated surges.
The maximum gradient of 10.73% changes the pacing equation. Even if the climb's average is moderate, those steeper pitches can force a rider out of their preferred cadence if they have overcommitted earlier. That is where this climb becomes selective. Not because every meter is hard, but because a long climb with sharper sections punishes poor energy management.
The start at 115 m also means the climb has a full vertical story to tell before topping out at 1337 m. The road gains enough height that the effort should be treated as a proper mountain ascent, not a rolling approach with a summit finish attached.
Pacing strategy
Ride the first part below ego. On a climb this long, the cost of starting too hard compounds quietly. If you use /glossary/ftp as a pacing anchor, the sensible approach is to settle into a controlled endurance-to-tempo rhythm early, then let the climb come to you.
Key pacing notes:
- Keep the opening effort deliberately restrained, even if the gradient feels forgiving.
- Avoid chasing speed on shallower sections, because the 10.73% maximum gradient means harder ramps are in the profile.
- Use the steadier portions to recover cadence and breathing, not to lift power unnecessarily.
- Save any sustained push for the final part of the climb, once the accumulated elevation gain is already largely paid for.
Gearing and ride feel
Choose gearing for the steepest section, not the average gradient. A 4.62% average can make riders under-gear for the climb, but the maximum pitch is steep enough that a bailout option is useful, especially after a long effort.
The ideal setup lets you stay seated and keep pressure smooth when the gradient rises. If you have to grind the steepest ramps after already climbing for a long time, muscular fatigue will arrive faster than cardiovascular fatigue. That is the real trap of Passo di Pietra Spada: it looks steady enough to ride aggressively, but its length and elevation gain make patience the faster strategy.
