Mo Farah admits this year's London Marathon is likely to be his last.
Britain’s most successful track athlete has been confirmed on the entry list for this year’s men’s elite race around the English capital.
Farah, who missed last year’s event through injury, will be 40 by the time the TCS London Marathon comes around on 23 April.
"It’s been an amazing career and taking part in the London Marathon is a very big deal," he said.
"I was gutted not to race last year and I just want to give it one more shot.
"It depends on my body. I just want to get to the start line and see what I can manage. I’m just taking one race at a time.
"I’m not a spring chicken any more. You can’t keep coming back in the right shape and, for me, I’d love to be able to finish it at home.
"We are getting closer to the end of my career, for sure."
Farah has ruled out a fourth Olympics in 2024, but acknowledged the lure of the World Championships in Budapest later this year.
"I’m not going to go to the Olympics and I think 2023 will be my last year," he added.
"But if it came down to it towards the end of the year and you did get picked for your country, I’d never turn that down.
"But like I say, I’m just taking it one race at a time and getting ready for the London Marathon, which is a big one."
