FunTrails Round, live.

Three trail distances in Chichibu and Okumusashi

FunTrails Round is a trail running event with three distances on the mountain trails of Chichibu and Okumusashi in Japan.

FunTrails Round is a trail running event in Chichibu and Okumusashi, organised by a local executive committee, and the 2026 edition is the 12th. It takes place on 14 and 15 November 2026. The organiser wants an event that everyone involved can enjoy, not only the participants. It aims to be kind to the environment, to share the trails with hikers, to be enjoyable for the staff, and to bring people and the region together.

The courses use mountain trails across Chichibu and Okumusashi, the same paths that hikers walk. On 9 November 2026 the organiser published a notice of course changes affecting FTR100MILE, FTR100K and FTR50K, so anyone taking part should check the organiser's course page and news for the current route. The organiser also publishes a participant agreement, health check and mandatory gear checklist in Japanese and English.

There are three distances. FTR100MILE covers 160 km, FTR100K covers 105 km and FTR50K covers 54 km. All three are recognised as ITRA and UTMB qualifying races, with 6, 5 and 3 ITRA points respectively and UTMB Index categories of 100M, 100K and 50K.

For people who come to watch or follow from home, the organiser points to its live results site, TRAIL SEARCH, and has posted a request about how to cheer during the event, which is worth reading before heading out to the trails. A person in the field can also choose to share their own live position on Livebib from their phone. This is not the organiser's timing, and official results come from the organiser.
