The Tojinbo Ai no Maranic is a 63 km running event in Sakai City, Fukui Prefecture, held in June with an early-morning start. Runners begin and end at Mikuni Gymnasium. The course is listed as flat, with 0 m of cumulative elevation gain. This is not a standard city marathon; the distance places it in ultra territory, and the word “maranic” suggests a long run where pace, food stops, and interaction are as important as racing the clock.
The time limit is 11 hours, including checkpoint cutoffs, requiring steady pacing and sufficient margin to continue throughout the day. The event emphasizes interaction among runners, volunteers, and the local community. Aid stations are a significant part of the event, with volunteers offering local Fukui food at many stops. It is also promoted as a travel-running event, appealing to runners seeking a long-distance race connected to a specific location rather than a closed-off, big-city road race.
