The concept of a backyard ultra is quite simple and has been encouraged by Gary Cantrell, aka Lazarus Lake and/or Laz, who founded both Big Backyard Ultra and the Barkley Marathons. Tartarus Backyard Ultra will follow closely to Laz’s original format. The concept is simple. It’s a last person standing race. In the end, only one runner will finish the race.
