Durango Trails Backyard Ultra

What is a Backyard Ultra?

A Backyard Ultra is also known as a Last Person Standing Race. Complete 4.17 miles of dirt road and single track trail every hour on the Spurline Trail system in Durango. Each 4.17 mile loop is referred to as a “yard.” If you finish in less than an hour- kick your feet up and snack until you line back up in the corral at the top of the hour to start again. Hour after hour, racers continue to line up until they tap out of the race or time out on a yard. The race is over when there is one runner remaining- that person must successfully complete one more hour to secure the win. Backyard races are for everyone! Complete just one yard, set a distance PR, or come out and compete for the win. Who will be the Durango Trails Backyard champion?!

Starting Procedure

There will be 3 whistles at three minutes, 2 at two minutes, 1 at one minute, thirty seconds called, and a ten second countdown, and then the starting cow bell. You must be inside the starting corral when the starting cow bell is given to start the hour. No late starts, no exceptions. Once the hour starts, you must start on the course and remain on it.

Restroom Rule

There will be a few porta potties at the main basecamp, racers may visit them whenever they are back to camp.

Personal Stations and Crew

Personal stations will be 8x8 or 10x10 spots. The base campsite is on dirt. Folks are strongly encouraged to bring weights and stakes for tents. There can be high winds in the high desert that will blow tents and shelters away. Early registration gives priority to tent placement- closer to the start and finish. You may request to be closer to other racers, and are more than welcome to share a space with someone. Bring friends and family to crew.

Parking and Set Up

Set up will be Friday, May 29th. More details to come.
