Col de la Croix Fry

Overview

The Col de la Croix Fry is a Category 1 climb in France, starting at 626 m elevation and finishing at the summit at 1,473 m. The road covers 17.4 km to deliver 1,259 m of total ascent — a substantial amount of vertical for a road that averages just 4.87%. That relatively modest average is misleading. A maximum gradient of 17.57% signals that the climb does not distribute its difficulty evenly, and riders who pace purely off the mean will get caught out.

Gradient Profile

With 17.4 km of road and 1,259 m of climbing, the Col de la Croix Fry rewards riders who read the road rather than ride to a fixed number. The average of 4.87% sits in a range that feels manageable for long stretches — sustainable at a solid tempo for experienced climbers — but the 17.57% maximum is in a different category entirely. Ramps at that pitch demand either a significant gear reserve or the ability to produce short, high-power efforts without blowing up the rest of your climb.

Expect the character of the road to shift. Sections near the average gradient allow you to settle into a rhythm and accumulate kilometers efficiently. The steep ramps, wherever they appear, are the moments that determine whether you arrive at 1,473 m with legs or without them.

Pacing Notes

• Ride the average, not the maximum. Target a power output sustainable across the full 17.4 km. If you don't know your FTP, use the FTP estimator before attempting a climb with this much elevation change.
• Protect your legs early. The total ascent of 1,259 m is high. Going deep into your reserves on the lower slopes to bank time will cost more than it gains on a climb of this length.
• Identify the steep ramps in advance. The 17.57% maximum means at least one section will require you to either stand and push a harder gear or spin a very low ratio seated. Neither approach is wrong — choose based on your strengths and how much road remains.
• Control your cadence on the sharp pitches. Grinding a big gear at 17% accelerates fatigue disproportionately. If your legs begin to slow below roughly 70 rpm on the steeps, shift down rather than force it.

Gearing

For most riders, a compact chainset (50/34) paired with an 11-32 or 11-34 cassette is a sensible starting point. The long stretches near the average gradient mean you will spend time in the mid-range of your cassette. However, the 17.57% maximum makes the bail-out end of that cassette — your 32 or 34 — genuinely necessary rather than just reassuring to have. Riders on a standard 53/39 setup should be confident in their ability to handle 17% on the small ring before committing to that configuration.

Summary

The Col de la Croix Fry is a long, uneven Category 1 climb that punishes naive pacing. The 4.87% average makes the early and middle kilometers feel approachable; the 17.57% maximum demands a gear reserve and the discipline to arrive at the steep sections with something left. Respect the 1,259 m of total ascent, ride within your sustainable output, and treat the flat or shallow sections as recovery, not as an invitation to accelerate.
