Col de la Ramaz

Overview

Col de la Ramaz is a Category 1 climb in France, measuring 14.4 km from base to summit with an average gradient of 6.58% and a net elevation gain of 950 m. The total ascent logged across the route reaches 1,449 m, meaning the road isn't a simple straight ramp — there are undulations that inflate the cumulative climbing well beyond the point-to-point elevation difference.

The starting elevation sits at 609 m. That relatively modest altitude means no meaningful thin-air penalty at the base, though riders should note the climb finishes at 1,559 m, where the air is noticeably thinner than valley roads.

Gradient Profile

The headline average of 6.58% is manageable on paper, but the 32.98% maximum gradient tells a very different story. That figure is extreme — well into the territory where most riders, regardless of fitness, will be grinding at near-zero speed or briefly forced to walk if caught in the wrong gear.

What to expect section by section

• Lower slopes: The climb opens from 609 m, and the early kilometres tend to set a moderate tone. Use this section to settle breathing, not to bank time. The 14.4 km total distance rewards patience.
• Mid-climb: With total ascent considerably exceeding net gain, expect rollers and short descents that reset the legs momentarily but don't let you fully recover. Resist the urge to accelerate on easier ramps — the hardest pitches are still ahead.
• Upper ramps: The sub-33% maximum gradient lurks somewhere in this climb. Even if it's a short wall, arriving at it with depleted glycogen and heavy legs is a serious problem. These ramps demand a gear low enough to keep pedalling at a sustainable cadence — ideally 60–70 rpm minimum — rather than stomping and blowing up.

Pacing Notes

With a 6.58% average over 14.4 km, this is a sustained effort well above threshold for most riders if attacked without restraint. The target approach:

• Set power early against FTP, not sensation. The opening kilometres can feel deceptively comfortable. Riders who pace to feel on Col de la Ramaz typically pay for it in the final third.
• Target 95–100% FTP as a ceiling for the bulk of the climb. Given the total ascent of 1,449 m and the near-33% maximum pitch waiting somewhere on route, saving a reserve is not conservative — it's necessary.
• Do not chase riders on the lower slopes. The climb is long enough that any gap opened in the first 5 km is unlikely to be decisive, but blowing up before the summit is.
• Use the undulations. Where gradient eases, recover breathing rather than accelerating. These are free recovery windows.

Gearing Recommendations

The 32.98% maximum gradient is the governing factor for gearing selection. A compact chainset (50/34 or 46/33) paired with a wide-range cassette — 32T minimum, 34T preferable — is strongly advised. Riders on standard 53/39 setups face a real risk of being unable to maintain a survivable cadence on the steepest pitch.

If you're unsure whether your current setup is adequate for gradients above 20%, use the FTP estimator to model your watts-per-kilogram and cross-reference against gear inches before committing to an attempt.

Summary

Col de la Ramaz earns its Category 1 rating through a combination of length (14.4 km), sustained gradient (6.58% average), significant total ascent (1,449 m), and a maximum pitch approaching 33%. Respect the early kilometres, gear conservatively, and treat the average gradient as a pacing ceiling rather than a target.
