White Man Pass

White Man Pass cycling climb profile

White Man Pass is a long Category 1 climb in CA, and the headline number can be slightly misleading if taken on its own. At 18.8 km with an average gradient of 5.04%, it looks like a steady endurance ascent. The problem is that the maximum gradient reaches 21.35%, which tells you this is not simply a metronomic five-percent climb from bottom to top.

The climb starts at 1213 m and finishes at 2159 m, gaining 946 m to the summit. That profile rewards riders who can keep pressure on the pedals for a long time, but it also punishes anyone who treats the average gradient as the whole story. A climb of this length already demands restraint. Add in ramps above twenty percent, and the pacing mistake becomes obvious: riding the early road at or above threshold leaves too little room to absorb the steepest sections without blowing up.

How the gradient shapes the ride

The 5.04% average suggests much of White Man Pass should feel manageable if paced correctly, especially for riders comfortable with long aerobic climbing. But the 21.35% maximum gradient changes the tactical equation. Even if those steep pitches are short, they force torque, cadence disruption, and repeated muscular load.

That means the best ride is not the fastest-feeling start. It is the ride that keeps the steepest ramps from becoming decisive. Stay under control early, avoid chasing speed on the more moderate gradients, and leave enough headroom to lift effort when the road kicks hard. On a climb this long, the cost of each over-threshold surge compounds.

Pacing and gearing notes

Use the first part of the climb to settle into a sustainable rhythm rather than trying to normalize the average gradient. If riding by power, anchor the effort around what you know you can hold for a long climb, then allow controlled rises on the steep ramps rather than fighting to keep the same cadence at any cost. Riders unsure of their sustainable climbing power should calibrate against /glossary/ftp or use /tools/ftp-estimator before targeting an effort.

Gearing should be chosen for the 21.35% maximum gradient, not the 5.04% average. A low climbing gear is the practical choice because it gives you options when cadence drops and the road steepens. Overgearing here turns the hardest sections into low-cadence strength work, which can drain the legs well before the summit.

The cleanest strategy is simple: ride the long middle of the climb with discipline, save matches for the steepest ramps, and only press harder once the summit is realistically within reach.
