Swimming 101: Competition Format | NBC Olympics

RELAYS

Each country can enter up to eight swimmers in each relay. In many cases, a country will have alternates swim in the prelims, allowing the fastest swimmers to be rested for the final. Athletes who swim in only the heats are awarded a medal if their country earns one in the final, meaning up to eight swimmers can win a medal for a relay.
