Colle Fauniera

Overview

Colle Fauniera is a hors catégorie (HC) climb in Italy, running 23.4 km from a start elevation of 749 m to a summit at 2,469 m. Over that distance it delivers a net elevation gain of 1,720 m at an average gradient of 7.35%. That combination of length and sustained pitch is what earns it the HC label: there is no single short wall to survive here, but a long grind that keeps you working for the better part of two hours.

The number to watch is the gap between net gain and total ascent. You climb 1,720 m net, but the road actually forces 2,394 m of ascent — roughly 674 m of extra climbing hidden inside descents you then have to reclaim. That undulation means the effort is higher than the average gradient implies. You pay for every metre you give back, and the losses compound the fatigue rather than offering true rest.

How the Gradient Unfolds

The 7.35% average hides real variation. Because the road undulates, some segments sit well below average while others spike hard, peaking at a 21.44% ramp that dwarfs anything a steady-state average suggests.

• Flatter and false-flat sections where you can recover briefly and eat
• Short descents that steal altitude, then repeated pitches to win it back
• Sustained mid-climb stretches above the 7.35% average
• A steepest ramp near 21.44% that demands your lowest gear

Pacing Notes

On a climb this undulating, chase even effort, not even speed. If you pin a target speed, the steep ramps will blow you past your sustainable power output and the flatter recovery zones will let you coast when you should be pressing. Hold steady power instead: ease the pace on the 21.44% pitches and keep pushing through the false flats where the effort feels easy but the metres add up.

Know your ceiling before you start. Use the FTP estimator to set a realistic threshold, then ride the steep sections a touch below it so you have something left for the upper slopes toward 2,469 m.

Gearing

The 21.44% maximum dictates your setup, not the average. Fit a compact or sub-compact chainset and a wide-range cassette — a 34×32 or 34×34 gives you the low end to spin the steepest ramp without grinding to a stall. On a 23.4 km climb, an over-geared setup turns short walls into muscular efforts you cannot afford to repeat. Check your chainrings and cassette before the ride; confirming the low gear now is far cheaper than discovering it halfway up.

Summary

• Length: 23.4 km
• Average gradient: 7.35%
• Maximum gradient: 21.44%
• Net elevation gain: 1,720 m
• Total ascent: 2,394 m
• Category: HC

Colle Fauniera rewards riders who respect its undulation. Pace by effort, gear for the 21.44% ramp, and treat the 674 m of reclaimed altitude as the real challenge behind the numbers.
