The Distance Medley Relay is an athletic event in which four athletes compete as part of a relay. Unlike most track relays, each member of the team runs a different distance. A Distance Medley Relay is made up of a 1200 meter leg, a 400 meter leg, an 800 meter leg, and a 1600 meter leg - in that order. The total distance run is 4000 meters or nearly 2.5 miles.
