Grand Valley Backyard

Grand Valley Backyard Ultra

Grand Valley Backyard Ultra is a true last person standing backyard ultra held at the 18 Road trailhead north of Fruita, Colorado. The event uses a loop of 4.167 miles (4 miles 880 feet, 6.7056 kilometers) that is mostly singletrack with some double track and no pavement. Each loop includes about 500 feet of elevation gain, primarily in the first half, and the course is described as non-technical and entirely runnable.

The format runs open-ended until only one runner completes a lap more than all others. Each loop must be completed within one hour and all competitors must start together at the bell; warnings are given 3, 2, and 1 minutes before the start. The winner is the last person to complete a loop; if no runner completes one more loop than anyone else, there is no winner. Timing of individual loops is optional.

Race logistics and rules note that competitors are largely self-sustained. The start and finish area is the only aid station. Organizers will provide water, an endurance fuel product, and coffee at night, and the event is cupless. No pacers, trekking poles, or dogs are allowed. Each runner may have up to three crew members who must remain in the start/finish area. Participants receive a race shirt and a custom finisher's buckle. Each runner is assigned a 10 by 10 foot area near the start and finish, and separate parking is provided for runners. Visit the organization's website for the most recent information.
