Onigajo 100 200km 2026
New in 2026: ten laps of the 20 km mountain loop from the Narukawa Gorge campground in Kihoku, Ehime. Each lap climbs from about 400 m to over 1,100 m, with aid only at the venue. Runners who pass the 8-lap (160 km) gate in time are recognised as 'mile finishers'.
The course tops out at 1,152 m (low point 434 m). Only about 20% is gentle (under 5% grade); most of it is climbing or descending.

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.
