The UTMF/STY are races as well as opportunities in which you will challenge your body and mind in a natural environment.
Are you well prepared? Have you carefully thought through what may happen during those 100/50 miles and are ready to solve any problems you may encounter?
Please read the race regulations once more and with the same enthusiasm as your training and decision on what equipment you’ll be bring with you.
We hope that the participants do not only follow the regulations but also understand the meaning behind the rules. The UTMF/STY races are not just about the individual.
The regulations are in place to guide the behavior of the participants so that trail running will be accepted and respected by Japanese society.
Please conduct yourself during the trail running race as if you were the President of International Trail Running Federation!
We hope you have a good race!
