(Reuters) - Five swimmers to watch out for at the Tokyo Olympics:
KATIE LEDECKY (UNITED STATES)
Ledecky has five golds from the past two Games and needs three more to equal retired compatriot Jenny Thompson's record eight for a female swimmer (1992-2000).
At Rio 2016 she won four golds and a silver and was the most decorated female athlete along with U.S. gymnast Simone Biles. In Tokyo she can win the 800m free for the third Games in a row, having first won it in London as a 15-year-old.
Ledecky, 24, also has 15 world championship golds and holds the world records for 400, 800 and 1,500m freestyle.
CAELEB DRESSEL (UNITED STATES)
A double Olympic relay gold medallist in 2016 and winner of 13 world championship golds, the 24-year-old sprint specialist is another U.S. medal machine.
In 2019 Dressel became the first swimmer to win eight medals at a single world championships and also took Olympic great Michael Phelps’s 10-year-old 100m butterfly world record for good measure.
He will be favourite in the 50 and 100m free and the 100m butterfly. Throw in the relays and he could be targeting seven golds.
ARIARNE TITMUS (AUSTRALIA)
The 20-year-old Tasmanian will be making her Olympic debut with plenty of expectation after winning two golds at the 2019 world championships including beating an unwell Ledecky to the 400m freestyle title.
She came back from a three-month layoff with a left shoulder problem by taking the 200m freestyle title at Australia's national championships in April.
The showdown between her and Ledecky, the two fastest women in 400m history, promises to be a highlight.
ADAM PEATY (BRITAIN)
The breaststroke specialist, the reigning Olympic champion and world record holder at 100m, is as close as it gets to a nailed-on certainty in the pool.
The 26-year-old Briton is the only man to have swum the 100m in under 58 seconds and he now has the top 20 fastest times in history. During the COVID-19 lockdown he had a pool installed in his back garden.
"For me, as a personal journey, it's all about breaking world records and going faster," the eight times world champion said in March.
KRISTOF MILAK (HUNGARY)
Olympic debutant Milak could be a threat to Dressel in the 100m butterfly and that duel will be eagerly awaited.
The 21-year-old is Hungary's rising star, taking some of the attention away from 'Iron Lady' compatriot Katinka Hosszu, after smashing Phelps's decade-old 200m butterfly world record at the 2019 worlds.
At the European championships in Budapest in May, he won the 200m fly by more than three seconds and posted the second fastest time ever in the distance.
