country favourite Ian Thorpe. Andorra, Belarus, Cyprus, the Czech Republic, India, Lithuania, and Trinidad and Tobago each made their debut in the event. Australia made its 11th appearance, the only nation to have competed in all prior editions of the event. Competition format The competition altered the format that had been used since 1984. The tournament expanded to three rounds: heats, semifinals, and a final. The advancement rule followed the format introduced in 1952. A swimmer's place in the heat was not used to determine advancement; instead, the fastest times from across all heats in a round were used. Instead of having the top 16 swimmers divided into a Final A for the top 8 and Final B for 9th through 16th, as was done in from 1984 to 1996, the 2000 competition added semifinals. The top 16 swimmers from the heats competed in the new semifinals. The top 8 semifinalists advanced to the final (there was no longer a classification final for 9th through 16th). Swim-offs were used as necessary to break ties. This swimming event used freestyle swimming, which means that the method of the stroke is not regulated (unlike backstroke, breaststroke, and butterfly events). Nearly all swimmers use the front crawl or a variant of that stroke. Because an Olympic-size swimming pool is 50 metres long, this race consisted of four lengths of the pool.
