Event overview

Revolution Running presents the 6th annual #onemileatatime, a Last Man Standing style event at Oxbow Meadows in Columbus, GA (3535 S. Lumpkin Rd). The format uses a 1 mile paved loop. The event in 2026 is held as a 12 hour format; the maximum possible distance is 50 miles for a runner who completes the final lap.

Format and rules

1 mile loop per lap.
Up to 50 miles total (final lap is mile 50).

Runners have exactly 15 minutes to complete each 1 mile loop. After completing a loop, a runner may not start the next loop until the 15 minute segment ends. A runner must be present in the start line corral when the bell sounds for the segment or they are removed from the event. This 15 minute schedule applies for the first 10 hours (40 miles). After that, the segment time is reduced by one minute every other lap until the final lap. If multiple runners reach the final lap, the fastest lap on that final circuit determines the winner.

Only water and electrolyte drinks are provided at the main aid station. Participants may set up their own tents and must bring their own food, supplies, and crew.

Registration closes Wed, Jun 17. The refund policy offers 100% refund until three months before the race date; after that there is no refund.
