Farah hopes to compete for World 5,000m and 10,000m titles
Double European champion Mo Farah could still compete in both the 5,000 and 10,000m at the World Championships.
The 28-year-old was quoted on Sunday as saying he was going to "put all my eggs in one basket and that is the 10k".
But the Londoner has now opened the door to running in both events at the championships, which start in Daegu, South Korea, on 27 August.
He said: "I meant to say it depends on how I come out of the 10k. If I feel good I will come back and do the 5k."
Farah has won his last nine races since moving with his wife and daughter to Portland, Oregon to be coached by three-time New York Marathon winner Alberto Salazar.
The Somali-born runner, who tops the world rankings for the 10,000m, puts his unbeaten record on the line when he runs the 3,000m at the London Grand Prix on Friday.
He added: "Things have been going really well and I'm really enjoying being based in Oregon.
"I just have to keep my feet on the ground. Where it matters is the World Championships."
Farah won the 5,000m at the UK Athletics trials for the World Championships on Sunday, clocking 14 minutes, 0.72 seconds.
