ONAGAWA 100 TRAILS 35km 2026
Also known as: Onagawa 100
Starting and finishing at WACK Onagawa Stadium in Onagawa, Miyagi, this category runs the south loop and the north loop once each. It includes part of the Michinoku Coastal Trail, with Pacific views from Mt. Ishinage and Mt. Kuromori, so you get both the sea and the mountains.
The course tops out at 458 m (low point 3 m). There are 2 big climbs: 405 m around 8–11 km; 455 m around 18–25 km. About 50% of the distance is gentle (under 5% grade). In 2026, 97% of starters finished. The median finish was about 6 h.

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.
