The Shinetsu Five Mountains Trail race  (SFMT),  produced by one of Japan's top trail runners - Hiroki Ishikawa, is one of Japan's most popular ultra-distance trail races . Now in it's 9th year, the 110 km race has sold out within hours every year since it started and is expected to sell out again for 2017. This year however, is particularly a very special year as a new 100 mile category has been added to the race!  


A dream come true - 100 miles!


This long awaited 100 miler will take racers deeper into the Myoko mountains and although very beautiful, will also be very challenging. As such, there are specific racer qualifications required to enter the 100 mile category (see Race Info section). If you have the quals, please come join us for this special inaugural race.  Also click here for a message from Hiroki Ishikawa explaining his 100 miler "dream come true".



International/Overseas Race Entries

The official Shinetsu Five Mountains Trail website is only available in Japanese. However, the race organizers would like to welcome participants from around the world and has asked Avid Adventures Japan to provide information about the race in English and to manage their international/overseas race entries.


This year the race will be held from September 16 -18, 2017. Registration starts on Sunday, June 11, 2017 at 21:00 JST (Japan Standard Time).

Non-Japanese racers living outside of Japan (or temporarily living in Japan) can sign up for the race on this website. Race slots will be filled on a first come first serve basis. 




About the Race

Shinetsu Five Mountains Trail

Mt. Madarao ~ Mt. Myoko ~ Mt. Kurohime ~ Mt. Togakushi ~ Mt. Iizuna


The Race Course

  • The 100 mile and 110 km race courses connects a series of five mountains collectively called the "Shinetsu Gogaku" located in the Niigata and Nagano prefectures.
  • Both courses were carefully designed to avoid steep slopes and fragile terrain in order to protect environmentally sensitive areas. Over 97% is on trail and much of the terrain is smooth and runnable.


Assistance Points, Pacers & Drop Bags

  • The 100 mile race has 7 assistance points (aid stations) and the 100 km race has 4 set up along the course where family and friends can provide support during the race. 
  • Food and drinks will be available at the aid stations. Parking spaces and an area where supporters can set up tables, chairs and tents will also be available. (Support cannot be provided outside these areas.)
  • Pacers are allowed to accompany racers for a section of the race. For the 100 mile category, pacers are allowed from Kurohime (102km) and for the 110km category, pacers can join their racers from the Sasagamine (63km) assistant point.
  • Drop bags can be left at Kurohime (102km) for the 100 mile category and Sasagamime (63km) for the 100km category. You can pick up additional gear or leave behind gear you no longer need during the race in these drop bags. Drop bags can be picked up after the race during the awards ceremony.



Consideration for the Environment

  • In order to minimize the impact on the environment, the race has limited the number of racers and conducts trail maintenance work both before and after the race.
  •  A portion of the race entry fees are also used to maintain the local trails and to support groups involved in environmental conservation activities.
