Colle di Caprauna

What to Expect on the Colle di Caprauna

The Colle di Caprauna is a Category 1 climb in the Italian Ligurian Alps that demands more respect than its average gradient suggests. At 22.3 km long with a net elevation gain of 1,100 m — starting at 274 m and finishing at 1,374 m — it looks manageable on paper. The 4.93% average is the number that will mislead you if you let it.

The key figure is total ascent: 2,207 m across a climb with only 1,100 m of net gain. That gap tells you everything. The road does not simply rise in a straight line. There are undulating sections, false flats, and brief descents that reset your legs temporarily but rob you of momentum and force repeated efforts above threshold. You are climbing nearly twice the net elevation gain before you reach the summit.

Gradient Profile

The 18.7% maximum gradient is the sharpest reminder that this climb has teeth. That kind of ramp appears without much warning on climbs with this profile type, and it likely occurs more than once given the significant difference between net gain and total ascent.

• Average gradient: 4.93% — moderate enough that riders sometimes push too hard early
• Max gradient: 18.7% — short but severe, requiring a low gear reserve
• Net elevation gain: 1,100 m over 22.3 km
• Total ascent: 2,207 m — the real workload indicator

Because the road loses and regains elevation repeatedly, you cannot treat this as a straightforward long grind. Efforts spike, recover, and spike again.

Pacing Notes

The length alone — 22.3 km — places this firmly in the category of climbs where FTP-based pacing is essential. Riders who target a fixed power output relative to their functional threshold will fare far better than those riding by feel or trying to match a gradient that keeps shifting.

Recommended approach:

• Set a ceiling of 75–80% of FTP for the first half. The undulating profile means your power will naturally spike on the steeper ramps; keep average power controlled.
• Reserve a gear for the steep pitches. With a max of 18.7%, you need a low enough ratio to stay seated and maintain cadence rather than grinding or standing for extended periods.
• Treat the descending sections as genuine recovery — soft pedalling, controlled breathing — not as opportunities to accelerate into the next ramp.
• The final kilometers to the 1,374 m summit will compound fatigue accumulated across the undulations. Start the last quarter with something left.

Gearing

Given the 18.7% maximum and the repeated nature of the steep pitches implied by the total ascent figure, a compact chainset (50/34) paired with an 11-32 or 11-34 cassette is the practical choice for most riders. Stronger climbers on a standard 52/36 setup should ensure they carry at least a 30-tooth sprocket. Getting caught in the wrong gear on a sudden steep ramp after a flat section is one of the more common mistakes on this type of climb.

Summary

Colle di Caprauna is a deceptive Category 1 climb. The 4.93% average understates the effort; the 2,207 m of total ascent and 18.7% maximum gradient reflect the real challenge. Ride it with a power target, keep gearing flexible, and do not trust the flat sections — they are temporary.
