TENGU100 100km 2026
The 100 km category starts and finishes at Mt. TAKAO BASE CAMP in Takao, Hachioji, Tokyo, and covers three laps of a roughly 30 km loop through Takao, Aihara and Tsukui. Organised by Ryuta-ren, it is a self-navigation race with only partial course marking. There are two aid stations: the venue and the Shiroyamako Community Center.
The course tops out at 403 m (low point 139 m). About 60% of the distance is gentle (under 5% grade), so there is a lot of running.

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.
