Jungle Guruguru MAX 120km 2026
Also known as: JGM 120km
The three-lap category of a lap-based endurance race in the satoyama hills of Oku-Musashi. From 2026 it starts and finishes at New Sunpia Saitama Ogose on a new course, and runners complete three laps of a roughly 43km loop linking Kanhasshu Miharashidai, Takayama Fudo and Kaburi Pass. The cutoff at the Hattoku aid on the last lap is set on the tight side. There are no course marshals, so self-navigation is expected.
7,614 m of climbing over 130 km (59 m per km).

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.
