BULSS 神奈川 (Backyard Ultra Last Samurai Standing) 2026
Held at Hadano Tanzawa Climbing Park in Hadano, at the foot of the Tanzawa range. Each yard is three out-and-backs on mostly paved road with some gravel forest road, so runners pass and cheer each other constantly. February nights get very cold.
A backyard ultra: a 6.706 km lap every 60 minutes (D+150 m per lap), until only one runner is left.
