RACES involve two or more competitors running against each other over a set distance. RELAYS involve teams of four runners who take turns running a set distance. DASHES are short-distance RACES, usually over 100 meters. Heats are preliminary RACES used to determine which athletes will advance to the final race. SPRINTS are short-distance RACES, usually over 200 meters.
