Overview
Held as a timed road race on a loop under 5km in Kobe, Hyogo Pref., Japan, the 6-hour relay & solo marathon Kobe was measured entirely by the clock rather than distance. Runners managed their own pacing and strategy within a fixed 6 limit.
First run in 2015 and organised by Japan Sport Consulting Co., Ltd., the event completed 10 editions through 2025. The short circuit kept support accessible on every lap across the duration. In 2025, 18 solo participants went the distance to complete the timed challenge.
