Kansas City Backyard Ultra
Kansas City Backyard Ultra is a Last Runner Standing format running event held in Kansas City, Missouri. The event takes place at Mill Creek Park on the Country Club Plaza with the start and finish near the J.C. Nichols Memorial Fountain.
Distances and formats:
- Last Runner Standing
- 12 hour event
- 9 hour event
- 6 hour event
- 3 hour event
The marked loop is made of four 1 mile laps, creating a four mile loop on a mondo like track surface. Runners pass a primary, abundantly stocked aid station each mile. Restrooms are available near the start and finish and runners have a small area near the start line to set up a chair. Water and coffee are provided for runners.
Basic rules follow the Backyard Ultra format. A runner must complete a full loop within the hour to be eligible to start the next loop and must be present in the start corral when the next hour begins. Crew assistance on course is not allowed and artificial aids such as trekking poles are prohibited. Each runner may have up to two crew members. The event records each runner's total miles rather than labeling a DNF on the record; one final runner who completes the final loop is declared the winner.
Last Runner Standing participants receive a Kansas City Backyard Ultra folding chair. All runners receive a buff, a cinch bag, and a finisher car sticker with their completed mileage. Visit the organization's website for the most recent information.
