第13回 津南ウルトラマラソン 80K／64K／48K 2026

The Tsunan Ultra Marathon is a summer ultramarathon held in Tsunan, a town within Niigata Prefecture’s Nakauonuma District. The race starts at New Greenpia Tsunan in Akinari, offering participants three long-distance options: 80K, 64K, and 48K. The event is now in its 13th year, marking it as an established local ultra. The available information suggests a straightforward mountain-town endurance event, with the primary appeal being the selection of three ultra distances from the single Tsunan base.
