Nui Po Au

Nui Po Au cycling climb profile

Nui Po Au is a short category 2 climb in China, but the headline number is enough to explain why it rides much harder than its 3 km length suggests. The average gradient is 10.91%, and the maximum gradient reaches 22.19%. That combination matters: this is not a climb where the main challenge is duration. The challenge is torque, traction, and avoiding a costly early overreach.

The climb starts at 1 m and tops out at 332 m, with a listed net elevation gain of 331 m. On paper, that makes the effort compact and direct. There is not enough distance for a long tactical reset, so the opening pacing decision shapes the whole climb. If you go above threshold too early, the steepest ramps will turn that mistake into a forced cadence drop rather than something you can smoothly absorb.

How the gradient rides

With the available profile data, the key point is the spread between the average and maximum gradient. An average of 10.91% over 3 km already means sustained climbing pressure. A maximum of 22.19% tells you there are sections steep enough to break rhythm and demand seated strength or short standing efforts.

That makes Nui Po Au a climb of repeated muscular load rather than a steady tempo climb. Even if the road settles back toward the average after the steepest pitches, the damage from those ramps can linger. The practical mistake is treating the first part like a three-kilometre test at a fixed power. The better read is to pace it as a steep climb with surges imposed by the road.

Pacing and gearing

The safest strategy is controlled aggression. Start below the power you think you can hold for the full climb, then let the gradient dictate where you spend matches. On gradients this steep, chasing a perfect power number can be misleading because cadence drops and torque rises even when power looks stable.

A compact climbing gear is the right call. The 22.19% maximum gradient is the deciding factor, not the 3 km length. If your gearing is too tall, the steepest sections become anaerobic by necessity, not choice. That is where riders lose time after the ramp, because they cannot return to an efficient cadence once the road eases.

Use seated climbing for control where possible, shift before the steepest changes in pitch, and stand only when it helps preserve cadence rather than rescue a bad gear choice. If using /glossary/ftp as a pacing anchor, think of the average grade as threshold pressure and the maximum grade as the reason to keep a reserve.

Nui Po Au is short enough to tempt a full-gas approach, but steep enough to punish it. The fastest ride is likely the one that looks restrained early, keeps cadence alive through the hardest ramps, and only spends fully once the summit is close.
