After running more than 600 kilometres in four days, Australian endurance athlete Phil Gore smashed the world record for the Backyard Ultramarathon event on a cattle farm in southern Queensland.


At the Dead Cow Gully Backyard Masters competition outside of Nanango, 180 kilometres northwest of Brisbane, Gore completed 102 laps, often known as loops.


Gore claimed that in the two months leading up to the race, he took cold showers to help him adapt to the weather.


The course’s organizers refer to it as a “race without a finish line,” and it calls for runners to complete a 6.7-kilometre circle every hour.


The race goes on until there is just one racer left.


At the competition, the final three runners all achieved national records.
