Matsumoto Pass

Overview

Matsumoto Pass is a short, steep Category 2 climb in Japan. It covers just 1.3 km, rising from a start elevation of 0 m to a summit at 169 m, for a net elevation gain of 169 m. On paper that reads as a brief effort, but the numbers underneath it tell a harder story: at 12.61% average gradient, this is a wall, not a warm-up.

The gap between the 169 m of net gain and the 245 m of total ascent matters. That 76 m difference means the road gives back roughly 76 m of descent across the climb — you are not simply going up. Every metre you drop is a metre you have to reclaim, and on a climb this steep the re-acceleration out of each dip costs disproportionate energy. Treat the total ascent, not the net gain, as the true measure of the work waiting for you.

How the Gradient Unfolds

The 12.61% average is deceptive because it flattens out both the recovery dips and the brutal ramps into a single tidy figure. With 245 m of total ascent packed into 1.3 km and 76 m of descent mixed in, the real profile swings well above and below the mean.

• Expect short recovery or downhill sections that account for the 76 m of give-back — do not treat them as rest, treat them as run-ups.
• Expect repeated short climbs stacked back to back rather than one steady grade.
• Expect the steepest ramp to sit well north of 12.61% — the pitches are where this climb earns its Category 2 rating.

Pacing Notes

On an undulating climb like this, even-speed pacing will wreck you. Chasing a constant km/h forces you to surge on every ramp and coast every dip, spiking your effort exactly where it hurts most. Aim instead for even effort: hold a steady, repeatable sustainable power output and let your speed rise and fall with the terrain. Ease slightly before each steep pitch so you arrive with headroom rather than already in the red. If you do not know your threshold, run the numbers through the FTP estimator before you commit to a target.

Gearing

The steepest gradient here demands respect. Gear for the ramps, not the average. Run a compact (50/34) or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 low gear gives you the cadence to spin over the steep pitches instead of grinding to a stall. Check your setup before the ride: confirm the cassette, derailleur capacity, and shifting are all dialled. A gear you cannot turn on a wall this steep is no gear at all.

Summary

• Length: 1.3 km
• Average gradient: 12.61%
• Net elevation gain: 169 m
• Total ascent: 245 m
• Category: 2

Matsumoto Pass is short but uncompromising: a Category 2 climb that punches well above its 1.3 km on the strength of its gradient and undulation. Pace it by effort, gear it for the steep ramps, and respect the extra work hidden in that 245 m of total ascent.
