Tarturus Backyard Ultra
9711 W Charles Rd., Nine Mile Falls WA, 99026, USA
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 and one Rucker will finish the race.
We’ve analyzed lots of data from weather and terrain and have found that Camp 7 and the month of August make the most ideal conditions for human potential in both running and rucking.
To be clear, these are two separate races. There is a running race and a rucking race. You can only participate in one or the other.
At 0800 hours, we will start a race at the old airstrip in Camp 7 and will use the local trails to complete the daytime loop that is 4.1667 miles (Runners) and 3.2 miles (Ruckers).
Each Runner and Rucker has exactly one-hour to complete the loop. We will start another race at 0900 hours, where Runners and Ruckers race around the same 4.1667 or 3.2 mile trail loop. The same will be done at 1000, 1100, 1200, and so on, every hour on the hour.
Runners and Ruckers must be standing in the start line corral when the next race starts. If you are out of the corral, you can not continue. Runners and Ruckers will also not continue if they self-eliminate. No late starts are allowed once the bell is rung.
Tartarus Races will continue until only one runner remains. At that point, the last Runner and Rucker must complete a loop on their own. If they can complete the loop than that person is the winner for either the Run or Ruck race. All other runners are considered Did Not Finish (DNF).
At 2000 hours, the races will be moved to an out-and-back course on the Centennial Trail. This will continue in likewise fashion every hour. At 0800 hours the next morning, the races will continue on the trail loop.
