about the race

Treat yourself to some of Nagano’s most spectacular views! Come on out to Sugadaira, a sleepy village tucked away in the mountainous regions of the Japan Alps, and run the race of a lifetime! Enjoy stunning landscapes as you traverse mountains, scramble down the ski slopes, and run above the clouds (yes, the air gets thin)! More than 90% is on trail and runners will encounter a broad range of terrain including gravel, silt, asphalt, large rocks, and even stairs. Most of the trail is moderately technical – both the climbs and descents are steep with unsteady footing.

Set at an elevation of approximately 1,100 meters, Sugadaira is home to several ski courses and a popular place for winter sports enthusiasts. Those seeking a reprieve from the concrete jungles of the city can bask in the cool breezes of early summer in Sugadaira – come on out and experience it for yourself!

Cut off times are generous but beginners may find the 22KM and 50KM overwhelming. Those with the weekend free will definitely want to challenge the Sanada Vertical 100 on Saturday afternoon!

Why does Samurai Sports implement a service charge? They help us cover the cost of operating the registration platform, translation of athlete guides/event information, labor hours required to answer your event inquiries, etc. Depending on the event, the surcharges help to cover the cost of our physical presence at the event. Learn more about Samurai Sports’ service charge. 

Note about Accommodation
The registration fee for the 50KM includes accommodation. All participants racing the 50KM on Sunday, June 9 must stay in the designated accommodation on the night before the race. Those registered for the Vertical 100, 5KM, and 22KM, do not need to stay the night at Nagano. However, we recommend and encourage athletes (and their companions) to stay the night and arrange for accommodation.

Why? Samurai Sports and Fields encourages all athletes (regardless of distance) and their companions to arrange for and stay in their designated accommodation. The race organizers believe that this allows runners adequate rest on the night before the race and helps to prevent injuries or accidents that may occur during a race, especially one in a high altitude environment. Relax and get ready for the race – it will be an early start!

Since Sugadaira is a very small town, Samurai Sports has provided an add-on option for accommodation. Each adult is ¥8,000 – for fees pertaining to special requests, children, etc., please view “Remarks” below. Additionally, it is helpful for us if you indicate additional and specific accommodation requests in the registration form. Samurai Sports will follow-up via email.

If your lodging circumstances have changed or need to be altered for any reason at all, please send us an email at info@samuraisports.co.jp
