Shiono Pass cycling climb profile
Shiono Pass is a compact but serious climbing test: 8 km at an average gradient of 7.18%, rising from 84 m to 659 m. That gives the climb enough vertical weight to punish overconfidence, while the 13.53% maximum gradient means the hardest moments are not just uncomfortable - they can materially change how the climb rides if you arrive at them already over threshold.
Listed as a category 1 climb, Shiono Pass sits in the range where pacing matters more than aggression. The average gradient is already high enough that there is limited free recovery, so the key is not simply surviving the steepest ramp. It is managing the accumulated load before that ramp arrives.
How the gradient feels
With an 8 km length and a 7.18% average, Shiono Pass should be approached as a sustained aerobic climb rather than a short power climb. The profile data does not describe individual bends or kilometre splits, so the safest reading is that the climb asks for steady pressure most of the way, with at least one section steep enough to reach 13.53%.
That maximum gradient is the important tactical detail. A climb can average 7.18% in different ways, but once the road touches 13.53%, gearing and pacing become decisive. If you ride the lower slopes too close to your limit, the steepest pitch will force a low-cadence grind, and that usually costs more than just the seconds lost on the ramp. It can push you above sustainable effort and make the upper part of the climb feel much longer than its 8 km distance suggests.
Pacing and gearing notes
Start controlled. On a climb with this average gradient, the opening effort should feel deliberately restrained, especially if riding by /glossary/ftp or heart rate. The goal is to keep enough margin that the steepest section can be ridden with pressure rather than panic.
A climbing-friendly gear choice is sensible here. The 13.53% maximum is steep enough that riders who are over-geared may be forced into muscular, low-cadence efforts. That is manageable for a short burst, but on an 8 km climb it becomes expensive if repeated or if it arrives late in the ascent.
Practical approach:
- Ride the first part below your target ceiling, not at it.
- Keep cadence smooth before the steepest pitch, even if that means resisting early surges.
- Expect the 13.53% maximum to demand a gear change before effort catches up with you.
- If pacing by power, avoid chasing speed on the steeper ground. Hold the effort and let the gradient dictate the pace.
What matters most
Shiono Pass is not defined by extreme length, but by the combination of sustained average gradient and a sharp maximum. The climb rewards riders who keep the effort even, protect cadence, and avoid turning the steepest section into an anaerobic effort. Treat it as a steady threshold-style ascent with one or more costly ramps, and it becomes a controlled test rather than a slow fade to the summit.
