Lazy A Backyard Ultra

The Lazy A Backyard Ultra is an endurance running event held in Udall, KS at 1868 E 60th Ave N. The format has runners complete repeated laps of a fixed distance, with each completed lap counted as one Yard. The standard lap distance is 4.167 miles (6.706 kilometers) so that 24 Yards equals 100 miles.

Each lap must be completed within one hour. Runners who do not finish a lap in the allowed time, who miss the required start for the next lap, or who withdraw are eliminated. The race continues until a single runner completes one more lap than all others; if no runner completes an extra lap beyond the others, there is no winner. The final winner must complete their last lap alone to be declared the winner. Runners who do not finish will have their total miles recorded rather than a DNF on official records.

Course and safety details note that the route uses public roadways, so runners should run on the left and be aware of traffic. Common aid stations are provided but no pacing or personal assistance is allowed on course; crew support is permitted only between laps at the start/finish area. Participants are responsible for their own hydration and fueling and should carry appropriate water or a hydration vest. After dark runners must wear a reflective vest and carry a light or headlamp. Dogs are not allowed on site for the comfort of farm animals.

Swag for participants includes a bib, a t-shirt, and a custom Lazy A medallion showing Yards completed. Winners in male, female, and non-binary categories receive free entry to the next year and a Lazy A railroad spike knife. Visit the organization's website for the most recent information.
