Kop Pass cycling climb profile
Kop Pass is a Category 2 climb in TR that asks for controlled, steady work rather than repeated violent accelerations. The headline numbers are straightforward: 10 km in length, 6.22 percent average gradient, and a summit at 2,413 m after starting at 1,793 m. That gives the climb its real character. It is not defined by a single savage wall, but by the need to keep producing power for a long enough stretch that early overpacing will be punished.
The average gradient sits in the range where most trained riders can find rhythm, but it is still steep enough that small pacing errors compound. A climb like this rewards discipline. If you ride the opening kilometres as if 6.22 percent is comfortable, the back half becomes more expensive, especially because the road finishes high. Even without treating altitude as a separate number to chase, the summit elevation tells you the final effort is happening well above the start, so the same power may feel less forgiving near the top.
How the gradient unfolds
The available stats point to a climb with a steady profile and a capped maximum gradient of 9.68 percent. That matters tactically. The hardest sections do not reach double-digit gradient, so the decisive factor is less about surviving ramps and more about avoiding a slow fade across the full 10 km.
The start at 1,793 m means you are already climbing from a high base. From there, the road gains 620 m to the summit at 2,413 m. The listed total ascent is 592 m, which is slightly lower than the net elevation gain implied by the start and summit elevations, so the most useful practical takeaway is simple: treat Kop Pass as roughly a six-hundred-metre climbing effort spread across 10 km.
That distribution creates a climb where momentum matters. On a pass averaging 6.22 percent, you can stay seated for long stretches and keep the effort aerobic if you respect the gradient. But the 9.68 percent maximum means there are pitches where torque rises, cadence drops, and the cost of riding over threshold can creep in quickly.
Pacing and gearing notes
Start conservatively. For the first part of the climb, ride below the effort you think you can hold to the summit, then let the grade and breathing confirm the pace. If you use /glossary/ftp as an anchor, this is the kind of climb where a smooth, sustainable threshold-adjacent effort is usually more valuable than surging into every steeper pitch.
Gearing should leave room for the maximum gradient rather than just the average. A setup that feels fine at 6.22 percent can become restrictive when the road lifts toward 9.68 percent, especially late in the climb. Prioritise a low enough gear to keep cadence under control without having to stand every time the gradient bites.
The key is patience. Kop Pass is long enough to expose poor pacing, steady enough to reward metronomic riding, and steep enough that efficiency matters from bottom to summit.
