Hakone marks the start of this overnight Ekiden-style run, focused on completing the outward leg of the Hakone Ekiden as a group instead of individually. The atmosphere is straightforward and shared: “This challenge will change you,” and “it’s difficult alone, but achievable with others.” It is suitable for beginners, families, and seasoned runners interested in observing and supporting the Shonan International Marathon while maintaining their own pace. Anticipate a lengthy, consistent group run at a relaxed, shared pace, with the Hakone Ekiden course dictating the day's structure. The steep final ascent from Hakone-Yumoto is intended to be walked, though running is permitted, reflecting the event's ethos. Aid stations and shops are available en route for anyone needing to withdraw, and the underlying benefit is that completing it will enhance your appreciation of the Hakone Ekiden.
