About the Event

Experience the refreshing autumn breeze and scenic beauty of Shiraishi City, one of Japan's premier pear-producing regions. This charming city invites runners to partake in its unique blend of athletic challenge and cultural appreciation.
The event features distances suitable for all levels: a 10km race for serious competitors, a more leisurely 5km route, and shorter options including a family-friendly 2km run and an additional middle school division. Each participant will have the opportunity to enjoy freshly picked pears from local orchards along the course.
Shiraishi City's picturesque landscapes offer runners stunning views of pear groves and rolling hills as they navigate through quiet streets lined with autumn foliage. The event promises a memorable experience, combining physical exertion with the sensory delights of Japan’s rich agricultural heritage.
Registration fees vary based on distance: 10km costs ¥6,000, 5km is priced at ¥5,000, and middle school entrants pay ¥3,000. The family-friendly option for two participants runs at ¥2,000 per person or a total of ¥3,000.
This event not only celebrates the beauty of Shiraishi City but also provides an opportunity to taste its renowned pears firsthand during the post-race festivities.
Join us this fall and immerse yourself in the delightful combination of sport and nature.
