Course Description

Mostly single trails, we have tried to make it as easy underfoot as possible so it conforms to the original concept of the Backyard Ultra’s as in it is more a mental challenge rather than physical. We have also tried to keep the elevation as close the original Big’s Backyard (145m) as possible, total elevation per lap of the Blister is 120m

How long is this likely to go on?

As this is the first event of this format in New South Walse we don’t know.  But as an example of how far this Last Person Standing event can go, some stats from the United States Big’s Backyard Ultra event in October 2018:

  • At 44 laps/hours 2 women and 5 men had completed 183miles (295km).
  • 3rd place Gavin Woody finished with 65 laps/hours completing 271miles (436km).
  • 2nd place Courtney Dauwalter finished with 67 laps/hours completing 279miles (449km).
  • Winner Johan Steene from Sweden completed one more lap to win in a new record of 68 laps covering 283miles (456km) in 68 hours!

Event Director of the United States event and founder of this type of event Laz Lake is renowned for dreaming up events to test people’s limits.  During the US event, Laz posts updates on the Facebook page throughout the event and he sums it all up as he wrote during the final hours…

it all comes down to johan steene and courtney dauwalter
one will get everything
and one will get nothing.
life is not fair in big’s backyard.
