About the race
The Bloomfield Backyard Ultra is a last-person-standing endurance race held in Bloomfield, Kentucky. The event uses a repeating loop of 4.167 miles that runners must complete within each hour; when the hour ends the lap must be finished and any remaining time can be used to rest and prepare for the next loop. There is no predetermined finish distance; runners continue until only one participant completes a final lap.
Race headquarters and the start/finish for each loop are at Bloomfield City Park. The route is primarily paved and runs through the heart of the Bloomfield community before returning to the park. The course is not closed to traffic, so runners should expect normal vehicle activity and are responsible for following traffic laws and staying alert at intersections and road crossings. Minor route adjustments may be made before race day for safety or logistics and will be communicated to entrants.
The event environment emphasizes local involvement, with neighbors, local businesses, volunteers, signs, and cowbells present along the route. The field typically shrinks over time as runners accumulate miles and the last remaining runner completes the final loop. Visit the organization's website for the most recent information.
