Passo del Faiallo

Overview

Passo del Faiallo is a Category 1 climb in Italy that runs 15.5 km from near sea level to its summit. The road starts at -2 m and tops out at 1,052 m, giving a net elevation gain of 1,054 m. On paper it reads as a long, steady grind at 6.8% average, and the near-sea-level start means you climb almost the full vertical range in a single, unbroken effort.

The number that reframes the whole climb is total ascent: 1,729 m of actual climbing against just 1,054 m of net gain. That gap of 675 m is descending folded into the route — the road repeatedly drops and reclimbs on its way up. You pay for every one of those extra metres, then pay again to regain the elevation you just lost. Treat this as a 1,729 m day of climbing, not a 1,054 m one, and budget your energy accordingly.

How the Gradient Unfolds

A 6.8% average is a lie of composition here. With 675 m of hidden descent, the true climbing pitches are steeper than the average implies — flat and downhill sections drag the mean down, so the parts that go up bite harder than 6.8%. The steepest ramp hits 22.85%, a wall that will force you out of any rhythm you've built.

• Recovery on the descents and false flats — use them to eat, drink, and shed heat
• Repeated short climbs stacked between the drops, each steeper than the posted average
• A maximum ramp of 22.85% that demands your lowest gear and a brief standing effort

Pacing Notes

On a smooth climb you'd pace by even effort. On Faiallo, the undulation makes even-speed pacing a trap: holding constant speed means spiking power on every reclimb and coasting the descents, which burns matches fast. Anchor instead to even effort around your sustainable power output, letting speed rise on the drops and fall on the ramps.

Do not chase a number on the 22.85% wall — brief surges above threshold there are unavoidable, so absorb them and settle back down after. If you don't know your ceiling, run the FTP estimator first and set a realistic target before the day starts.

Gearing

The 22.85% maximum governs your setup. That gradient will overwhelm a standard chainset at climbing cadence, so fit a compact (34-tooth inner) or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you the low gear to spin the steepest ramp instead of grinding it. Check your chainset and cassette before you ride; a gear you don't have is the one thing you can't fix on the wall.

Summary

• Length: 15.5 km
• Average gradient: 6.8%
• Maximum gradient: 22.85%
• Net elevation gain: 1,054 m
• Total ascent: 1,729 m
• Category: 1

Passo del Faiallo is longer in effort than its net gain suggests — 1,729 m of climbing hidden inside 15.5 km. Pace by effort, gear low for the 22.85% wall, and respect the 675 m of reclimbing that separates this from an ordinary Cat-1.
