Queeny Backyard Ultra

Queeny Backyard Ultra

Queeny Backyard Ultra is a backyard style ultramarathon held at Queeny Park in Saint Louis, Missouri. The event uses a Last Person Standing format where runners complete repeated loops until one runner finishes the final required lap and is declared the overall winner.

The park address is 1675 South Mason Road, Saint Louis, MO 63131. The park entrance is on Mason Road and the parking lot is located to the left inside the park. Race headquarters and setup are by the restrooms; canopy and tent space is available across from the restrooms past a white fence. The course connects from the paved trail onto Hawk Ridge Trail.

The event offers overall finisher awards in three divisions: Non-Binary, Female, and Male. Runners who do not win are typically classified as Did Not Finish and may receive a challenge coin based on loops completed:

• 12-18 Loops (50 to 75 miles): Bronze Challenge Coin
• 19-23 Loops (79 to 96 miles): Silver Challenge Coin
• 24 or more Loops (100+ miles): Gold Challenge Coin

Race registration includes custom race swag, all weekend camping, free photo downloads, and a post-race beer. The event partnered with the Trail Mix Fund to cover registration fees for runners who cannot afford them or who may feel under-represented in the sport. The 2026 edition was designated a Silver Ticket edition; that edition’s winner earned a Silver Ticket to the World Team Competition at Big's.
