Furbutt's Backyard 24 Hour and 12 Hour

Furbutt's Backyard is a backyard ultra held at Mustang Trailhead. The event follows the Backyard format with a set one hour loop and a 24 hour time limit and a 12 hour nighttime option. Entry is open and limited to 100 runners. Fees are charged to cover event expenses.

  • 24 hour format with a 100 mile limit
  • 12 hour after dark option with a 50 mile limit

Each loop is about 4.167 miles and runners must return to the start corral at the top of the next hour to begin the next loop. The course begins on a flat grassy field for about 0.7 miles then continues on dirt and crushed gravel bridle trails that are mostly flat with some gentle ups and downs. Total elevation gain per loop is about 300 to 350 feet.

Organizers provide water, ice, Gatorade, and some snacks. Runners are responsible for their own food and personal aid station supplies. A horse trailer pavilion covers the start and finish area and all runners are within a five to ten second walk of the start. Crews are allowed only at the single aid station and parking is in the grass field behind the pavilion.

This event does not provide medical care. No medical personnel or medical supplies are available on course and runners are responsible for their own health and safety. Emergency response may be distant or delayed and injuries such as cuts, bruises, dislocations, sprains, bee stings, and asthma attacks have occurred at similar events.
