Haute Route Challenge 70 km 2026
Also known as: Koshu Alps Haute Route
A loop that leaves Enzan in Koshu City before dawn and circles via Kamihikawa Pass, Yunosawa Pass, Ryumon Gorge and Fukasawa. Over 80% trail and nearly all singletrack, it follows ridges facing Mt. Fuji and repeated climbs through beech and mizunara forest.
The course tops out at 1,995 m (low point 458 m). There are 2 big climbs: 1,537 m around 4–25 km; 688 m around 41–49 km. About 30% of the distance is gentle (under 5% grade). In 2025, 73% of starters finished. The median finish was about 15 h, through one night.

Enter your ITRA performance index to get an estimated finish time, aid-station splits and cutoff margins. This race has no finisher ITRA data, so it uses the transfer model: your predictions for the 205 races that do have finisher data, scaled by distance and elevation gain (km-effort) — the same calculation as the TRAIL STATUS app. Nothing is saved or sent.
The app adds predictions from your training log (Strava), race-day pacing and more. Free, no sign-up.
