We sat down with Mollie O'Callaghan, the Australian youngster who won 6 medals at the world champs in Budapest. She describes her experience last year in Tokyo swimming and how swimming on only prelims relays kept her motivated heading into 2022. O'Callaghan also reveals that she was not originally a freestyle specialist, her 100 and 200 only coming around to a world-class level in the past 2 years.
