JMC Running Co: Solo-Ultra Challenge

The JMC Running Co: 5-Hour Relay & Solo-Ultra Challenge is an annual event held in Phoenixville, Pennsylvania, at Charlestown Park. Participants can choose between two events: a 5-person relay or a solo ultra challenge. The relay teams of five runners each complete repeated loops of approximately 2.2 miles over five hours, handing off to teammates in sequence.

Solo ultra runners aim to complete as many loops as possible within the same timeframe, testing endurance and determination. The course starts and finishes at pavilion #2, where a camp setup supports participants. The event offers a fun, competitive atmosphere with cash prizes, food, and water provided throughout the evening. Visit the organization's website for the most recent information.
