Wada Pass

Overview

Wada Pass is a Category 2 climb in Japan, running 10.2 km from a start elevation of 169 m to a summit of 699 m. That gives a net elevation gain of 530 m over the ascent. On paper it reads as a steady mid-length climb, and the 5.18% average gradient supports that first impression.

The number that changes the story is total ascent. While the net gain is 530 m, the climb accumulates 771 m of total ascent — a difference of 241 m. That gap means the road does not rise cleanly; it gives back roughly 241 m of descending before clawing it back on the way up. In practical terms, this is an undulating climb, and every metre you lose to a dip you have to pay for again. Expect the effort to feel harder than a smooth 5.18% grade would suggest.

How the Gradient Unfolds

The 5.18% average is a blend of very different terrain. Undulation of this magnitude tells you the profile hides both recovery and punchy pitches inside that average. The steep sections will run well above 5.18%, offset by flatter or downhill stretches that drag the mean down.

• Flatter and recovery sections where the road eases or briefly descends, accounting for the 241 m of give-back
• Repeated short climbs rather than one continuous wall, each one resetting your rhythm
• The steepest ramps, which sit meaningfully above the average and demand a change of gear and cadence

Pacing Notes

On an undulating climb like this, even-effort beats even-speed. Chasing a constant speed forces you to spike hard over every short rise and then coast the dips, burning matches you will want later. Instead, hold a steady sustainable power output and let your speed rise and fall with the terrain — faster on the flatter give-back sections, slower on the ramps, but effort held level throughout.

Because 771 m of total ascent is stacked into a 10.2 km climb, the accumulated work is what will decide your time, not any single pitch. If you don't know your ceiling, run the numbers through the FTP estimator first and set a target you can hold for the full 10.2 km.

Gearing

The steep ramps govern your gearing here. Even with a 5.18% average, the pitches above it will overload a standard road setup at climbing cadence. Fit a compact or sub-compact chainset paired with a wide-range cassette — a 34×32 or 34×34 gives you the low gear to spin the steepest ramps without grinding to a stall. Check your setup before the ride: confirm the cassette clears the rear derailleur and that you can actually reach that bottom gear under load. The undulation means you will shift constantly, so a clean-shifting drivetrain matters as much as the range.

Summary

• Length: 10.2 km
• Average gradient: 5.18%
• Net elevation gain: 530 m
• Total ascent: 771 m
• Category: 2

Wada Pass rewards riders who pace by effort and gear for the ramps rather than the average. Respect the 241 m of undulation, hold steady power, and the Category 2 label will feel earned rather than surprising.
