UTMF 170km

The UTMF is one of Japan's premier ultra-trail running races that takes racers around the mountains surrounding Mt. Fuji. It's part of the Ultra-Trail World Tour (UTWT) international ultra-trail running series and is the largest trail race in Japan.

Avid Adventures has been UTMF's official international tour partner since the very start of the UTMF and we will be offering racer accommodation & support packages again for 2019!

We look forward to seeing you in Mt. Fuji!




63km & 37km

The Kirishima Ebino-Kougen Extreme Trail is an exciting trail race located in the Kyushu area in southern Japan. There are two categories - a long and short course, and both courses will take you some of the most beautiful mountains within the Kirishima National Park.


The official race website has added an English website where we've translated all the race details and registration information. Overseas racers will be able to register for the race from the Avid website (starting the week of Feb 19 - please check back again soon!).

110km & 100 miles

Official race website:  www.sfmt100.com

Registrations for 2018 started on Sunday, June 10, 2018 at 21:00 JST and is expected to be around the same timing for 2019.

Please check back for details or sign up for our mailing list below for updates!



The Shinetsu Five Mountains Trail (SFMT) race is one of the most popular ultra-trail running races in Japan that sells out within minutes every year. Last year a new 100 mile (160km+) category was introduced in addition to the 110km race. Unfortunately the 100 mile category was shortend due to bad weather so the 2018 race should be the very first challenge for this particular distance.


As the race does not have an English website, the race organizers have asked us to provide an official translation on our Avid website. As the official SFMT International Help desk, we will also be responding to any questions you might have about the race  so feel free to drop us a line anytime!


Overseas racers can sign up for the race through this website (30 slots available on a first come first serve basis).
