Coquihalla Pass

Coquihalla Pass cycling climb profile

Coquihalla Pass is a long, high-consequence climbing effort rather than a short test of punch. The climb runs 16.5 km, starts at 790 m, and tops out at 1631 m, with 841 m of net elevation gain. On paper, the 5.11% average gradient looks manageable, but that number is only useful if it is treated as the baseline, not the full story.

The key detail is the 9.52% maximum gradient. A climb with this length and a near-double-digit maximum asks for restraint because the cost of over-riding the steadier sections compounds quickly. If you ride the average as if it is the ceiling, the steeper ramps will force repeated surges above sustainable power, which is exactly how a long climb turns from controlled to defensive.

How the gradient unfolds

The available profile gives the big shape clearly: this is a continuous bottom-to-summit ascent from 790 m to 1631 m across 16.5 km. It does not identify exactly where the steepest 9.52% pitch appears, so the smart read is tactical rather than decorative. Expect the climb to feel mostly governed by its 5.11% average, but pace it as if sharper ramps can arrive at any point.

That matters because a Category 1 climb of this length rewards riders who keep the effort narrow. The average gradient is not savage, but the duration means even small pacing errors become expensive. The gradient ceiling tells you there are sections where cadence can fall and torque demand rises. Those are not the places to prove form early. They are the places to stay seated if possible, keep pressure smooth, and avoid turning each ramp into an attack on your own legs.

Pacing and gearing notes

Use the first part of the climb to settle below your limit, not to bank time. A 16.5 km ascent gives plenty of road for the effort to mature, and the 841 m net gain means the summit will not arrive quickly if you go too deep too soon.

Practical approach:

• Start controlled, especially if the opening gradient feels easier than the 5.11% average suggests.
• Hold a sustainable climbing rhythm and let speed vary with the road.
• Keep a gear available for the 9.52% maximum gradient, not just the average.
• Avoid low-cadence grinding on the steepest sections unless that is already your strength.
• If riding by power, anchor the effort around threshold discipline rather than chasing pace. See /glossary/ftp if you use FTP to set climbing zones.

The best way to ride Coquihalla Pass is to respect the gap between average and maximum gradient. The climb is not defined by one brutal wall. It is defined by length, elevation gain, and the need to absorb steeper pitches without letting them dictate the whole ride.
