Sometimes the winner finishes last.


Anywhere in the world!


The Endurance Evolution Backyard Ultra is a race with no pre-determined finish line nor finish distance. It's also a virtual race.


Here's the deal. First map out a 4.167 mile loop or out and back course (preferably starting/finishing near your home).  Then on race day at 8:00 AM ET you'll start running that 4.167 mile course (and all other competitors will do the same wherever they are), and you have 60 minutes to finish it. It doesn't matter if it takes you 20 minutes, or 59 minutes and 59 seconds.  You just have to finish in 60 minutes.

Then at precisely 9:00 AM ET you'll head out and run that lap again.  Then at 10:00, 11:00, get the idea. No late starts are allowed - everyone starts at the top of the hour.

When you fail to start or complete a lap within 60 minutes, you're done, out, DNF. The last competitor to still be in the race, and finish a lap in 60 minutes or less is the winner. 

This is a virtual event, and each competitor will be running their own course, wherever they are.  Are you gunning for fast times and a top finish place? Plan out a flat route.  Are you looking to really challenge yourself?  Plan out a hilly course.  It's all up to you.

The Backyard Mini Ultra runners will do the exact same thing, but with a 3.14 mile course.
