Ledecky-Titmus swimming rivalry set to resume with revival of Duel in the Pool

• Match-race series to return in August for first time since 2007
• Big names to face off as Australia meet USA in Sydney

World swimming superpowers Australia and the United States will square off at a Duel in the Pool competition in Sydney this August. The nations, who collected 50 swimming medals between them at last year's Tokyo Olympics, are revisiting a made-for-TV concept last held in 2007.

Australia and the US will send 30 swimmers each to compete at Sydney's Olympic aquatic centre and Bondi Beach for open-water events. Swimming Australia says new race and relay formats will be among fresh bells and whistles at the meet as the sport seeks to broaden its audience.
