Mo Farah will compete in Monaco on 17 July in what will be his first race since doping allegations were made against his coach Alberto Salazar.
Farah, 32, withdrew from a 1500m race in Birmingham on 7 June because he felt "physically and emotionally drained".
A BBC investigation has alleged that Alberto Salazar, who coaches the double Olympic champion, has practised doping techniques with US athlete Galen Rupp.
There is no suggestion Briton Farah has been involved in doping.
Both Salazar and Rupp have denied the allegations made by the BBC's Panorama programme earlier this month.
After pulling out of the Diamond League meeting in Birmingham, Farah returned to the United States to spend time with his family and "seek answers" about the claims.
On Wednesday, he posted a picture of himself on Twitter while training in France.
"Good to be out on the track in France today, getting ready for my next race in Monaco!! Focusing on my training," tweeted the Briton.
The documentary - "Catch Me If You Can" - aired claims that Rupp, 29, was given the banned anabolic steroid testosterone in 2002, when he was 16 years old.
No allegations were made against other Nike Oregon Project athletes in the investigation.
In a news conference on the eve of the Birmingham Grand Prix, Farah said his name had been unfairly dragged into the story and claimed he had never witnessed any wrongdoing by the 56-year-old coach.
Farah, who has won Olympic and world titles since joining Salazar's set-up in 2011, has not spoken since pulling out the race in Birmingham, but apologised to fans on Facebook for not competing and added he was feeling "more upbeat" about things.
The reigning world and Olympic 5,000m and 10,000m champion is set to compete at the Sainsbury's Anniversary Games at the London Olympic Stadium at the end of July.
