Marysville Mini Backyard Ultra - Spring Edition
The Marysville Mini Backyard Ultra Spring Edition is scheduled for March 21, 2026, at Mill Valley Park, South Entrance in Marysville, Ohio. The event uses the standard Backyard Ultra format: runners complete a loop that begins at the top of each hour and repeats every hour until the event closes or until one runner remains.
The staging area and the start/finish line are located on the west side of the Mill Valley Park South Entrance. Parking is directed to the Mill Valley Park South Entrance. The event listing notes a runners guide is available for participants.
This is a self supported event. Competitors must provide their own hydration and nutrition during the race because event staff will not provide support. The event fee is listed as $10 and registration closes on March 18, 2026.
The published schedule for the day includes bib pickup, time for personal canopy setup, a brief meeting to review race procedures, and the repeating hourly loops that define the Backyard Ultra format. The race continues under that hourly loop structure until the published close time or until the last participant remains running. Visit the organization's website for the most recent information.
