Mark Cavendish is unlikely to return to the track for the 2016 Olympics, says British cycling chief Shane Sutton.
Cavendish was considering taking part in the omnium at the Rio Games in his quest for an Olympic medal after missing out in 2008 and 2012.
But the 29-year-old Manxman looks set to extend his road career and Sutton doubts he will change his mind.
"Unfortunately I think it is the end of the road. I think he has made his decision not to entertain it," he said.
Cavendish, a two-time track world champion, has focused largely on road racing since riding in the Madison, now discontinued at Olympic level, in Beijing in 2008.
Changes to the format of the omnium were believed to make that event attractive for a possible track return.
But while Sutton says "the door is open for Cavendish" he thinks time is running out for him to acquire the necessary qualification points.
Sutton added: "There is no cut-off date. The road ends when he can't numerically qualify, simple as that. But if he doesn't put the points on the board he can't qualify."
Cavendish admitted himself last month that his hopes of racing in Rio were probably over.
