- Record approx. 3,800 participants from 34 countries and regions to race while viewing Mt. Fuji

- FUJI100mi and ASUMI40k become World Trail Majors annual ranking races
Mt. FUJI 100 will hold its 11th event over three days from April 25 (Friday) to 27 (Sunday), 2025. In addition to the "FUJI100mi" (168.0km distance, 6,254m cumulative elevation gain) which traverses the mountains, forests, and towns at the foot of Mt. Fuji, and the "KAI70k" (70.2km distance, 3,052m cumulative elevation gain) covering the latter half of the course, this year introduces the new "ASUMI40k" (40.2km distance, 1,445m cumulative elevation gain). The total number of participants across the three races reaches approximately 3,800, the highest in the event's history since its first edition in 2012.
As the host of Japan's leading international trail running event, the Mt. Fuji area welcomes trail runners and their families.
Mt. FUJI 100 Enters its Second Year as a Key Race in the Gran Canaria World Trail Majors
Renamed last year, Mt. FUJI 100 enters its second year as a member of the international trail running series "Gran Canaria World Trail Majors." This year, in addition to the FUJI100mi, the newly established ASUMI40k will be included in the World Trail Majors' newly created "Short Series," a series for middle-distance races, attracting further international attention as an annual ranking race.
The 2025 Mt. FUJI 100 gathers participants from a record 45 countries and regions worldwide. Among them, 530 participants are from Asian countries and regions, including China, Hong Kong, Thailand, and South Korea. This reflects the growing popularity of trail running in Asia and shows that this event is growing as a platform for sharing the appeal and values of trail running across borders and celebrating each other's efforts.
The Course Around the Active Volcano Mt. Fuji is Varied and Challenging
The course for Mt. FUJI 100 is set in the foothill area surrounding Japan's highest peak, Mt. Fuji. In contrast to the desolate summit area, only 300 years since its last eruption, the foothill area is a trail running paradise dotted with mountains and forests covered in lush greenery and clear lakes. Meanwhile, Mt. Fuji has long been revered as a symbol of great nature and an object of worship, and towns prospered at its base to host pilgrims gathering from all over Japan. You might feel this history in the townscapes that appear between sections of the course.
Regarding the characteristics of the Mt. FUJI 100 course from a trail running perspective, Dylan Bowman (USA), the champion in 2016 and 2018, commented, "What makes Mt. Fuji unique is the alternation between flat, runnable sections and long stretches of tough climbs and descents." After climbing up and down steep slopes over rocks and tree roots, long sections of undulating trails and paved roads follow, requiring athletes to balance not just running ability but also pacing.
Course Partially Changed This Year, New 40km Race Added
The 2025 event will again feature Fuji Hokuroku Park Fujisan Meisui Stadium (Fujiyoshida City, Yamanashi Prefecture) as the main venue. It will serve as the finish for the FUJI100mi, which starts from Fujisan Kodomo no Kuni (Fuji City, Shizuoka Prefecture) on the south side of Mt. Fuji, as well as the start and finish point for the KAI70k and ASUMI40k.
Different from last year, the FUJI100mi will start at 17:00 on Friday, April 25 (Wave 1), with four waves starting every 15 minutes. The ASUMI40k will start at 12:00 on Saturday, April 26, and the KAI70k will start at 13:30 on the same day.
The newly established ASUMI40k uses a course that connects parts of the KAI70k course by short-cutting the middle section. This 40.2km race corresponds to the marathon-distance trail running category, which has seen a rapid increase in global participation and a remarkable improvement in competitive levels. It is expected not only to serve as an introductory race for this event, allowing runners to enjoy views of Mt. Fuji, but also to become an international-level competitive event, similar to the FUJI100mi and KAI70k.
