Bessang Pass

Bessang Pass cycling climb profile

Bessang Pass is a Category 1 climb that asks for patience more than aggression. On paper, the headline is straightforward: 18.7 km at an average gradient of 6.16%, rising from 204 m to 1,356 m. That gives the climb a large start-to-summit gain of 1,152 m, with total ascent listed at 1,084 m. However the numbers are framed, this is not a short ramp where a rider can bluff through on freshness. It is a long, aerobic climb where pacing discipline matters from the first sustained gradient.

How the gradient rides

The key detail is the gap between the average gradient and the maximum gradient. A 6.16% average over 18.7 km is already enough to make the climb selective, but the maximum gradient of 12.03% changes how it should be ridden. The average does not mean the effort will feel even. It means the climb has enough sustained uphill work to keep pressure on the legs, while the steepest pitches can force a sharp rise in torque and heart rate if you arrive over-geared or already too close to threshold.

With no sector-by-sector gradient data, the cleanest reading is this: Bessang Pass should be treated as a long steady climb with hard ramps, not as a punchy climb where the steepest section defines the whole effort. The danger is not one isolated 12.03% pitch. The danger is stacking small accelerations and gear-grinding moments across nearly 19 km until the final third becomes survival.

Pacing strategy

The correct pacing model is conservative early, controlled through the middle, and only aggressive once the summit is realistically close. For riders pacing by /glossary/ftp, the opening section should feel deliberately restrained. If it feels like a race effort too soon, the climb is probably being over-ridden.

Use the average gradient as a warning, not a target. At 6.16%, the climb will reward a smooth tempo, but the 12.03% maximum means there will be moments where power naturally rises. Let those ramps lift effort briefly, then settle back down rather than trying to hold the surge over the top. That reset is what keeps the climb aerobic instead of turning it into repeated threshold spikes.

Gearing notes

Choose gearing for the steepest ramps, not the average. A setup that feels comfortable at 6.16% can become inefficient when the road reaches 12.03%, especially late in an 18.7 km ascent. The goal is to keep cadence stable enough to stay seated and avoid muscular overload.

If you are unsure, err on the side of a lower climbing gear. Bessang Pass has enough length and elevation gain that saving torque matters. The rider who can keep pedaling smoothly through the steepest sections will usually finish stronger than the rider who treats the early gradients as an invitation to push.
