The Backyard Ultra is a last person standing Endurance Race.
– Riverhead Backyard ReLaps Ultra describe a Backyard Ultra like this…
A Backyard Ultra is a type of ultramarathon where participants run laps of a set course of 6.706 metres (4.167 miles) and they must finish each loop in less than an hour. The race restarts each hour with all those that finished the previous lap on time. The race is over when only one runner remains to complete a lap. This runner is marked as the winner and only finisher, with all other runners receiving a DNF (Did Not Finish). The strange distance is because the distance for 24 laps is equal to 100 miles.

Another way of saying what & how a Backyard Ultra rolls, is described below by ducklings Steve & Chris from The Best Dam Backyard Ultra in Otematata – Home of the NZ World Championship.
A Backyard Ultra is a form of running event where competitors try to consecutively run a loop measuring 6.7km in less than one hour.
Inch Events
Each competitor chooses how quickly they run the loop (known as a yard) and when each yard is completed, the remaining time within the hour is typically used to recover before the next yard starts on the hour.
Competitors complete as many yards as they can and the winner is the last person to complete a lap within the allocated hour.

“…the backyard format is so different to your point to point race for a number of reasons. One is the social aspect, because the gun doesn’t go off & you’re not rushing to get round, so there’s a lot of time out there to chat to your other runners & get to know each-other.
Fiona Hayvice NZ – Dead Cow Gully 2023.
And really, at the end of the day, it’s a game against yourself. You’re up against yourself & your own mind, so that’s really different to your point to point standard race.”
Fiona is founder of M.A.S.H Backyard Ultra NZ Kāpiti Coast.
