Six-time Olympic champion Jason Kenny is contemplating retirement, his wife Laura Kenny said on Friday.
The 29-year-old Bolton rider won three Olympic golds in Rio last August to draw level with fellow cyclist Sir Chris Hoy as Great Britain's most successful Olympian with six golds and one silver.
Kenny is absent from this week's Track Cycling World Championships in Hong Kong, taking an extended break post-Olympics as he considers whether to continue to the Tokyo 2020 Games or to quit altogether.
Four-time Olympic champion Laura Kenny told BBC Sport: "He's having six months to decide what he wants to do, whether to carry on or whether to retire.
"I'm not sure he even knows to be totally honest. As athletes, you always want to carry on, you always want to go to the next one.
"He's going to give himself a bit of time.
"As athletes you become this self-absorbed kind of person and everything's just about you, but there's bigger things in life than that."
Laura Kenny was working as a pundit on BBC's coverage of the competition, as she is now pregnant with the couple's first child.
Jason Kenny emulated Hoy to become just the third Briton in 108 years to win three Olympic golds at one Games.
The plan was always for Jason Kenny to have an extended sabbatical post-Rio, which was his third Olympics.
He won Olympic team sprint gold at the Beijing 2008 Games, where he finished with sprint silver behind Hoy aged 20.
Kenny was selected ahead of Hoy in the sprint four years later in London and justified the call by winning gold, as well as team sprint gold again.
And in Rio he took a hat-trick of titles with victories in the team sprint, sprint and Keirin. He married Laura (nee Trott) last September.
