Valico di San Fermo

Overview

Valico di San Fermo is a Category 1 climb in Italy, running 9.6 km from a start elevation of 513 m to a summit at 1150 m. Over that distance it delivers a net elevation gain of 637 m at an average gradient of 6.62%. On paper that reads as a steady tempo effort, and for long stretches it is — but the average is only part of the story.

The gap between the net gain and the total ascent is where this climb bites. You gain 637 m of altitude, but you actually climb 890 m — a difference of 253 m. That extra vertical is spent re-climbing ground you lost on descents and false flats along the way. Practically, it means more total work than the net figure implies, and it means your rhythm gets interrupted rather than settling into one long grind.

How the Gradient Unfolds

The 6.62% average hides real variation. With a maximum gradient of 22.05%, the climb has at least one pitch more than three times steeper than its average — and to keep the average where it is, there must be genuine easing elsewhere. Expect an uneven road rather than a uniform wall.

• Flatter and recovery sections where the road eases or briefly tips downhill, accounting for the extra 253 m of total ascent
• Repeated short climbs that break your cadence and force repeated re-accelerations
• A single steepest ramp near 22% that demands your lowest gear and a deliberate change of pace

Pacing Notes

On a uniform climb you can hold near-constant power and let speed drift with the slope. San Fermo's undulation makes that harder: on the flatter and descending parts, holding a fixed power target wastes energy for little altitude, while the steep pitches spike your effort well above threshold.

Pace to your sustainable power output, not to your speed. Ride the true climbing sections at a controlled tempo, ease off the pressure over the flatter rollers and descents instead of forcing power, then accept a short surge on the 22% ramp rather than trying to smooth it out. If you do not know your ceiling, run the numbers through the FTP estimator before you commit to a target for the day.

Gearing

The steepest gradient governs your setup. A 22.05% ramp will grind almost any standard gearing to a halt, so bring a compact (34-tooth inner) or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you a bailout for that ramp while keeping usable ratios for the tempo sections. Check your chainring and cassette combination before the ride, not at the base of the climb.

Summary

• Length: 9.6 km
• Average gradient: 6.62%
• Maximum gradient: 22.05%
• Net elevation gain: 637 m
• Total ascent: 890 m
• Category: 1

Valico di San Fermo rewards riders who respect the difference between its net gain and its total ascent. Pace to power, gear for the steepest ramp, and let the rollers work for you rather than against you.
