This year's trail race on Shiraishi Island will take place Sunday, May 7th during Japan's Golden Week holiday period. Sign-ups will be available on runnet.com as well as some other outlets. I'll let you know as soon as the links are available for sign-ups. If you cannot sign up via these Japanese sites, please contact us at Shiraishireservations at yahoo dot com and we'll help sign you up in English!
The proceeds of the race go to help maintain the 340-year-old Buddhist Pilgrimage on the island (which is a replica of the 88-Temple pilgrimage in Shikoku). Yoroshikuonegaishimasu!
