The Queeny Backyard Ultra returns to Queeny Park in St. Louis, Missouri on March 5th, 2027, offering runners a unique "Last Person Standing" challenge. Participants will gather at Smith Shelter within Queeny Park for the start of this ultra endurance event. The race begins early morning with temperatures expected around freezing and slight winds blowing from the north. Runners should be prepared to face firm trail conditions on both paved paths and dirt sections, alongside a UV index that is moderate but still requires sun protection. Since its inception in 2025 as part of Terrain Trail Runners-STL's initiative, the Queeny Backyard Ultra has become an integral event for promoting diversity within trail running. It supports the Trail Mix Fund, which waives race fees and encourages underrepresented groups to participate in racing communities. The event aims to foster a more inclusive environment by providing opportunities that might otherwise be financially or culturally out of reach. The course winds through Queeny Park's scenic trails including Hawk Ridge, Fox Run, White Oak, and Owl Creek Trails, all run counter-clockwise for a loop distance approximating 4.19 miles with significant elevation changes. This challenging terrain features rolling hills, wide paved paths, short dirt sections, and hardpacked stone/gravel trails. Weather conditions on race day are expected to be chilly with temperatures ranging from around freezing in the morning to slightly warmer as the sun rises higher. UV exposure will remain moderate throughout the day, requiring runners to wear protective clothing or sunscreen during their run. The risk of precipitation is minimal but not unheard of for this time of year.

Bib pickup will take place on March 4th from 9:00 AM until 6:00 PM at Queeny Park's Smith Shelter where participants should bring a valid photo ID and proof of payment if needed. For those unable to attend the bib pick up event, contact information for alternative arrangements can be found within pre-race emails sent out in late February. The race will start promptly on March 5th from 10 AM at 550 Weidman Road, Manchester, Missouri. Age requirements are open to all adult runners who meet the physical demands of this challenging ultra endurance event format. For first-time participants, it is recommended that they arrive early and familiarize themselves with both the trail layout provided in pre-race emails as well as any additional instructions given by race organizers.
