Welcome to Avid Adventures Japan!


Avid Adventures Japan works closely with the race organizers of some of Japan's premier trail running races to help them introduce their race to a broader international audience. Trail running is a wonderful way to come and experience the beautiful mountains and local culture of Japan and we're excited to be able to open up opportunities for racers coming from overseas to participate in these amazing races!


Depending on the race, we provide some or all of the following services:

 - Overseas racer registration

 - International help desk & communications

 - International media support

 - Race Packages that include accommodations and transportation to/from the race



Here's our race lineup for 2018!

We are proud to present four of the most iconic and popular races in Japan.

If you have any questions regarding the race, registration and/or the packages, please feel free to contact us anytime.

We look forward to making your trip to Japan an unforgettable one!




UTMF 170km / STY 92km

April 27 -  29, 2018  (Yamanashi & Shizuoka Prefectures)

Official race website: www.ultratrailmtfuji.com


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.


Although the race skipped one year and wasn't held in 2017, it's back in full force for 2018 with an exciting new course! There are two races, the UTMF (170km) & STY (92km) and both are expected to sell-out quickly. 


As the UTMF's official international tour partner, Avid has been providing racer support packages every year since the start of the race and will be doing so again for 2018.




Thank you very much for participating in UTMF/STY 2018!

Avid team is pround of the great performance of everyone who ran the race.

We look forward to seeing you again next year.

New race added this year!



63km & 37km

July 21-22, 2018   (Miyazaki & Kagoshima Prefectures / Kyushu)

Official race website:  http://universal-field.com/event/kirishima-ebino-extr/


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!).


Race accommodation & transportation details will also be available on the official website. 


Registrations for 2018 Kirishima Ebino-Kougen Extreme Trail are now open. Please see below.



110km & 100 miles

September 15-17, 2018   (Nagano & Niigata Prefectures)

Official race website:  www.sfmt100.com


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). 

New update! (as of 2018/6/6)

Registrations for 2018 starts on Sunday, June 10, 2018 at 21:00 Japan Standard Time.

Registration in English for international participants can be done through Avid Adventures from this website.

We are currently preparing a translation of the official website and the registration page which will be available within the next few days.
