In February 2019, Farah announced he planned to run again in the London Big Half Marathon in March 2019.
In an interview, he also stated that he is considering competing in the Tokyo Olympics in 2020, which, if confirmed, would mark his fourth Olympic games.
As well as stating that this would depend on whether his wife and kids "let him", he reflected on his track retirement, saying:
“I was honest and said I was done with the track but part of me missed it.
I feel like I can still win medals and do as well as I have over the years.”

He has also confirmed that he may run in the 10,000 metres at the World Championships in Doha in late 2019, although this would depend on the result of the 2019 Big Half Marathon.
This possibility was later confirmed by Neil Black, performance director of British Athletics, who has said that Farah had received financial backing from the National Lottery in anticipation for both his participation in the Championships, as well as for the Tokyo Olympics.

On 10 March 2019, Farah won his second London Big Half Marathon, and again hinted at running the 10,000m at the World Championships in October 2019.
In April, Farah finished in 5th place in the 2019 London Marathon in 2:05:39.

On 8 September 2019, Farah won the 2019 Great North Run for a record 6th consecutive time in a new Personal best of 59:07.

On 29 November 2019, Farah announced via his YouTube channel, his plan to return to the track to defend his 10,000m olympic title at the Tokyo 2020 Olympic games.
Farah stated he would put his marathon career on hold while he returned to track oriented training.
