Sir Mo Farah's coach has hinted the 35-year-old could be tempted by a return to the track at next year's World Championships.
The four-time Olympic champion won his first major marathon title in Chicago on Sunday, setting a new European record of two hours five minutes and 11 seconds.
He has turned his attention to road racing after calling time on his track career last year.
But his coach Gary Lough was quoted as saying by several national newspapers: "I think he will sit down with a few of us and look at his general plan for next year.
"He really wants to run the World Championships, but what he runs at the World Championships hasn't been decided."
Next year's Worlds take place in Doha in the autumn and the marathon would be the only road race available there to Farah, who in the build-up to the race in Chicago declared his intention to compete in the marathon at the 2020 Tokyo Olympics.
Lough added: "He might change things up a bit next year and surprise a few people, so we will see."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
