B loop


Osorakan Snow Park-Mt.Osorakan-Mt.Jippou-Nasu-Mt. Uchiguro pass-Osorakan Snow Park

This longest course is the most difficult of the three with the biggest accumulated elevation difference.
Make sure you plan your race thoroughly since you are expected to have hard time keeping up your pace with extreme ups and downs on the highly mountanious course in which you have to walk in some parts. Please keep that in mind when you run the race.
Daidokoro-Hara (Kitchen Field) located in beech forest on Mt. Osorakan and Sky Trail on Mt. Jippou are about the only relief and consolation through the strenuous race.
