WATER SPORT NEWS - Ainslie, 41, who won four Olympic gold medals between 2000 and 2012 as well as the America's Cup in 2013, has never attempted the round-the-world feat.
"It's always been on my radar because my dad raced in the first ever Whitbread Race in 1973," he told BBC Sport.
Ainslie will start his 2021 America's Cup campaign later this year.
His father, Roddy, was the skipper of Second Life, which finished seventh in the inaugural edition of the Whitbread Round-the-World Race, which is now known as the Volvo Ocean Race.
"I grew up with all these stories of ocean racing from the round-the-world race," Ainslie said. "My key ambitions were to go to the Olympics, win the America's Cup, and win the Whitbread Race."
