The Quantico Tri features a start near Officer’s Candidate School, a 750 meter open water swim in the Potomac River, and a 20K (12.4 mile) cycle tour of the Marine Corps Base, founded in 1917. The Quantico Tri will conclude with a 5K run, the distance every Marine must complete annually as part of the Marine Corps physical fitness test. For those desiring only to run, the MCM introduces the Quantico 12K to be hosted alongside the Quantico Tri. The run is a perfect distance at the perfect time in MCM training.
