Yunoo Pass

Yunoo Pass cycling climb profile

Yunoo Pass is a compact Category 4 climb in Japan, measuring 2.9 km at an average gradient of 5.84%. It starts at 41 m and tops out at 208 m, giving a net elevation gain of 167 m. The profile data lists total ascent at 151 m, so the clean takeaway is simple: this is a short, moderate climb where the main challenge is not survival, but resisting the urge to over-ride the opening minutes.

The defining number is the relationship between the average gradient and the maximum gradient. With an average of 5.84% and a maximum of 7.9%, Yunoo Pass does not appear to be a climb built around violent ramps or sustained wall-like pitches. Instead, it sits in the zone where most trained riders can stay seated, keep pressure on the pedals, and make meaningful time through pacing discipline rather than force.

How the gradient rides

Across 2.9 km, the climb is long enough to punish a sloppy start but short enough that it can be ridden assertively if you know your limits. The average gradient sits just under the point where momentum disappears completely, which means carrying speed into the lower slopes matters. But because the maximum gradient reaches 7.9%, there is enough resistance to expose anyone who starts as if the whole climb will stay gentle.

The practical reading is that Yunoo Pass should be treated as a steady threshold-style effort, not a punchy hill sprint. If the road is sitting near the average, the correct sensation is controlled pressure: breathing elevated, legs loaded, but cadence still stable. When the grade edges toward the steeper end of the profile, the goal is to absorb the change without spiking power too sharply.

That matters because on a climb this short, a hard acceleration over a steeper section feels cheap in the moment, then costs disproportionately near the summit. The rider who keeps the effort flatter will usually arrive at the top with better speed and less accumulated fatigue.

Pacing and gearing notes

Start slightly under the effort you think you can hold. The climb is only 2.9 km, so there is time to build, but not much time to recover from a mistake. Use the first part to settle breathing and cadence, then lift the effort once the rhythm is established.

A sensible approach:

• Ride the opening at controlled tempo, especially if fresh legs make the gradient feel easier than it is.
• Shift early before the steeper sections so cadence does not collapse near the 7.9% maximum.
• Stay seated for most of the climb unless a brief standing change helps reset the legs.
• If pacing by power, anchor the effort around your sustainable climbing output rather than chasing every change in gradient. See /glossary/ftp if you use FTP to structure efforts.

Yunoo Pass is not a climb that demands extreme gearing, but it does reward having a low enough gear to keep pedaling smoothly at close to 8%. Overgearing turns a manageable Category 4 ascent into a muscular grind, which is rarely faster on a climb this length.

Bottom line

Yunoo Pass is a short, controlled climb: 2.9 km, moderate average gradient, no listed pitch above 7.9%, and enough elevation gain to require proper pacing. Ride it with restraint at the bottom, stay smooth through the steeper moments, and save the real push for the final part rather than spending it too early.
