The ultimate backyard ultra marathon event
Dead Cow
Located on a 6th generation cattle property in rural Queensland, this Backyard Ultra Marathon is like no other. You will test your limits in a place where the cattle roam free and the gullies run dry. 6.7km, each hour, every hour until the last one is standing. The question is, are YOU ready TO TEST YOUR LIMITS?

Memories
"I came up with the concept of the big backyard ultra some 50 years ago, while I was still a young runner just starting out. 4.166667 miles an hour, every hour until only one man is standing. You cannot have a bad hour. Only good and great ones."
Gary Cantrell AKA ‘Lazarus Lake’‘Big’s Backyard Ultra’ 
‘Dead Cow Gully’ is named for the unfortunate beast that lost its footing close to the creek’s edge and was discovered a week later tangled in some protruding tree roots – 2 metres above the creek bed.
