The More Miles Last One Standing Challenge

The More Miles Last One Standing Challenge is an endurance running event held in Knoxville, Maryland, featuring a unique "last one standing" format. Participants run a 4.167-mile loop, known as "the yard," every hour on the hour, continuing as long as they can complete the loop within the hour. The event also offers a 1-mile version designed for beginners, kids, and walkers, with a festive atmosphere and extra time between laps.

The challenge serves as a qualifier for the Backyard Ultra world championship. In 2025, prize money will be awarded to the top two finishers based on total miles run, encouraging competitors to push beyond 100 miles in 24 hours. Visit the organization's website for the most recent information.
