Queeny Backyard Ultra

The Queeny Backyard Ultra is a unique "Last Person Standing" ultramarathon held at Queeny Park in St. Louis, Missouri. The race features a 4.19-mile loop with approximately 430 feet of elevation gain and loss, combining paved, dirt, and gravel trails through scenic park areas.

Participants must complete each loop within one hour and continue running successive loops until only one runner remains. The event emphasizes self-sufficiency, allowing limited crew support and no aid on the course. It is a cup-free, environmentally conscious race with awards for the last man and woman standing, and challenge coins for various mileage milestones.

Amenities include camping, free photos, and post-race beer. Visit the organization's website for the most recent information.
