A relay race consists of four sprints of equal distance combined. Each equal distance is referred to as a leg, and it is this distance that each of four teammates must run. The anchor is the last person to run in a relay. Medley relays are races in which the legs are of varying lengths. A 4×100-meter (40-yard) medley relay has two legs of 50 meters and two of 100 meters. A 4×200-meter (220-yard) medley relay has one leg of 100 meters, one of 200 meters, one of 100 meters, and one of 200 meters. The anchor's duty is to secure one end of a cable at the starting line. After the starter gives the go signal, the anchor runs with the rope attached, pulling the other team members across the finish line. To stop the clock during handoffs, the anchor signals "stop" by raising his arm over his head. The team members then release their grip on the rope and roll away from the cable to avoid being penalized for false starts. 3 an active anchor is any member of the sending team who has been designated as such.
