Race planning
Plan Backyard Ultra Last Samurai Standing Tokyo
Use the listed edition as your starting point. Each tool keeps imported race facts separate from the targets and assumptions you choose.
Edition notes: This is the backyard running race, not the 2025 Netflix drama of the same English title. The organizer’s 2026 schedule lists Tokyo as a Bronze race with general entry; the published entry window ran from July 18 to 11:59 PM Japan time on October 20, 2026 and has closed. The page lists a minimum of 20 runners but also says it will cancel with 20 or fewer; confirm the race’s go-ahead with the organizer. Big’s race page also lists November 21, 2026 at 13:00 and labels the race Bronze, but it still shows a 54-yard course record from 2020 and a 30-runner capacity. Yardlore lists the 2026 edition on November 1. Yards completed here count toward Big’s At-Large list, which takes the best results between August 16, 2025 and August 15, 2027.

- Backyard Ultra
- Distance
- 6.706 km every hour

- Duration / cutoff
- Each 6.706 km yard must be finished within the hour. Yards start exactly on the hour, with whistles 3, 2 and 1 minutes before, and every runner must leave the start area on the signal. No fixed finish: the last runner must complete an additional yard alone. If nobody does, there is no winner.

- Up to two support crew per runner, free and interchangeable. Crew may use only the toilets, kitchen and meeting room at Takao Green Center, and may not sleep in the meeting room. Help is allowed only between yards; any support during a yard means disqualification.
- Drop bags
- Check the current race rules
