About the Event
This autumn, join fellow runners for an unforgettable two-day celebration along the scenic coast of Shonan! The festivities kick off with a series of races designed to cater to all levels and ages. On day one, participants can choose from several race options: a 10km road race through picturesque coastal paths, a family-friendly run that encourages parents and children alike to enjoy the beauty of Shonan together, or a dedicated kids' event for young runners eager to experience the thrill of racing. The second day features endurance challenges like the 24-hour team relay and solo events spanning various durations including 12 hours, 6 hours, and even shorter bursts such as 4-hour races. Each race promises an immersive journey through Shonan's stunning landscapes, with routes that wind past iconic landmarks and serene beaches. The event is more than just a series of runs; it’s a community gathering where runners can connect, share stories, and celebrate the joy of running together in one of Japan's most beautiful coastal regions. Whether you're aiming for personal bests or simply enjoying the camaraderie among participants, this two-day extravaganza offers something unique for everyone involved. Registration fees vary depending on the race type: $45 (10km), $9 ($1 = 138 JPY) for both kids and family runs. For endurance events, costs range from $72 per team member in a 4-hour relay to $260 for an individual participating in the full 24 hours. Don't miss out on this opportunity to immerse yourself in Shonan's vibrant running culture! Join us and experience the magic of autumn along the coast.
