AMAGASE 128K 2027
Also known as: Amagase
A new category for 2027: eight laps of a roughly 16km marked loop from Tonoshima island in Uji Park, Kyoto, via Mt. Daikichi, Kominami Shrine and the Kisenyama Dam. It sits between the 80km and the 100-miler, with a generous 33.5-hour limit that runs through the night; you pass the venue every lap and can use a drop bag.
The course tops out at 378 m (low point 18 m). About 40% of the distance is gentle (under 5% grade).

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 287 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.
