Double Beijing Olympic swimming champion Rebecca Adlington has yet to decide whether she will compete at the Rio Games in 2016.
The 23-year-old Briton was quoted in the Mail on Sunday as saying: "Rio is out of reach. I'll be 27 then.
"Swimming, especially for distance swimmers, is a young person's game."
However, her mum Kay told BBC Radio Nottingham: "Given her age, it's highly unlikely she'll compete in Rio, but no final decision has been made."
She said Adlington could focus on shorter events in the future, adding: "She'll make a decision after her charity bike ride in October."
“If I were to race in Glasgow it would be in the 200m and 400m but definitely not the 800m. I'm done with that distance”
won freestyle gold over 400m
800m in Beijing
in 2008 and she
won bronze in both events
at London 2012, where she was beaten by 15-year-old American Katie Ledecky in the 800m freestyle.
The newspaper article, which was also carried on the British Olympic Association website, said Adlington had also not decided whether to compete in the 2014 Commonwealth Games in Glasgow.
"If I was a sprinter then I would go to Rio. But I don't have an ounce of sprinting in me," she said.
"If I were to race in Glasgow - and that's an if - then it would be in the 200m and 400m but definitely not the 800m. I'm done with that distance.
"I'd like to be in Rio, though, even if I'm just a fan. Hopefully I can be a bit more than that, like a mentor, or have some kind of official or unofficial role with the British swimming team."
The Mansfield swimmer, who is
taking part in a 450km charity bike ride across Zambia
next month, must also decide whether she will target a place in the Great Britain team at next year's World Championships in Barcelona.
Adlington said after the Olympics that
she needed a break "mentally and physically"
before making a decision on her future.
