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.

This awesome film from Find Your Feet Films gives a great narration of what the backyard ultra format is all about, while following the 2023 Riverhead ReLaps Backyard Ultra. Who better to narrate such a film than, Backyard Ultra Founder, Lazarus Lake, who attended the event. Laz shares his thoughts on what it takes to compete and succeed in the Backyard.

Backyard Ultra World Team Championships

There are currently 3 NZ Backyard ultras that are official silver ticket events (Pigs, ReLaps and Krayzies) and this means that the winners of each of these events automatically get selected in the NZ World Team Backyard Champs which are held every second year (the next one is on October 2024). The rest of the 15 person team is made up from the at-large list which is the highest number of loops run in any official backyard ultra between August 16, 2022 and ends August 15, 2024 .

You can see the top 15 people that would make the NZ team for 2024 here by filtering for the country NZ. This is kept up to date based on results from each qualifying backyard ultra. The current 15 person team looks like this:

Backyard Ultra World Individual Championships
