Navy Hospital Apprentice Sampson Mwangi, hailing from Kenya, Africa, presents his trophy as the Cherry Point duathlon Sept. 15. The Duathalon began with a three-mile run up and down Roosevelt Boulevard, beginning at the Marine Corps Air Station Cherry Point Hancock Pool.The more than 100 participants returned to Hancock Pool to board bikes for a 10-mile ride across the base and back. Dropping their bikes, the racers left nothing in their metaphorical gas tanks, pushing through a second three-mile run to complete the 16-mile course to the finish.
