About the Race

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

The Race Course

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

Assistant Points, Pacers & Drop Bags

  • The race has four assistance points (aid stations) set up along the course where family and friends can provide support during the race.
  • Food, drinks and a massage service 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.
  • Pacers are allowed to accompany racers for the last 45 km during which most racers will be running at night. Pacers are optional but having one can help boost performance and safety during the race.
  • Racers can leave a drop bag at Aid Station #5 (63.1km) to pick up additional gear or leave behind gear you no longer need during the race.


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.
