Farah, who withdrew from last year's event due to injury, has run the London Marathon three times with a best finish of third in 2018, the same year he won the Chicago Marathon.

"I'm not going to go to the Olympics and I think 2023 will probably be my last year," said Farah, who turns 40 in March. "It has been an amazing career and, for me, to take part in London Marathon is a big deal.

"I have always said it would be nice to win it one day, but it takes a lot ... It is just nice to say goodbye and I think it will be quite emotional.

"I am very proud of what I have achieved and I just want to give myself one more shot and see what I can do. But I have nothing to prove."

Farah will be joined by reigning Commonwealth Games 10,000 metres champion Eilish McColgan (32), who also withdrew ahead of her debut last year due to a medical issue. She is the daughter of the 1996 winner Liz McColgan.

"It was disappointing not to have taken part in last year's London Marathon. I had such a fantastic summer on the track and the plan was always to follow that with my marathon debut in London," the 2021 Birmingham Games gold medallist said.

"But I have been able to take further time to fully prepare for running a marathon and April will come around very quickly so I am extremely excited.

"The London Marathon is obviously a special event for me and my family with my mum having won the 1996 race and I just can't wait to experience it for myself."

The race will be held on the streets of London on April 23rd. The full elite field will be announced on Wednesday.
