One Mile With a Smile 12 Hour Endurance Run 2026

The One Mile With a Smile 12 Hour Endurance Run is a timed ultra held at Oak Grove Lake Park in Chesapeake, Virginia. Participants begin near 7 AM and have 12 hours to complete as many laps as possible on a 1.5-mile gravel loop encircling the lake. With approximately 60 participants, the event resembles a supported long run rather than a large competition, serving as a practical training opportunity for longer ultras. The loop course allows runners easy access to their supplies, including gear, food, chairs, and coolers. The day focuses on pacing and self-care alongside running. Early race conditions can be influenced by heat and humidity, leading some runners to adopt steady intervals, such as running for four minutes followed by a 1.5-minute walk, while consuming food consistently to maintain momentum. The field comprises endurance athletes seeking extended time on their feet, with some individuals increasing the challenge by pulling tires during the run.
