Plan MAS*H Backyard Ultra

Use the listed edition as your starting point. Each tool keeps imported race facts separate from the targets and assumptions you choose.

Listed edition: Jan 23, 2027
Format: Backyard Ultra
Distance: 6.71 km every hour
Local start time: 9:00 AM Saturday, January 23 (NZDT)
Duration / cutoff: Each 6.71 km yard must be finished within 60 minutes; no fixed overall finish. Warning whistles sound 3, 2 and 1 minutes before each start, runners must be inside the corral before the horn, and there are no late starts. The last runner to complete a yard alone wins; if nobody completes one more yard than everyone else, there is no winner.
Crew and pacers: Crews are welcome and may help only between yards, not inside the starting corral or during a yard. No pacing, accompanying or cycling alongside runners, and no trekking poles or other artificial aids. Runners must carry a headlamp and a mobile phone in the dark.
Drop bags: Check the current race rules
