Kieren Fallon has admitted his days as a rider are numbered and that he may yet consider a new career as a trainer.
The six-time champion jockey, who has had turbulent times over the years, is now 47 and although he he can count on rides from the likes of Luca Cumani, he does not have regular support from a very top stables.
"I don't think I'll have many (years left)," said Fallon, who was a late replacement for the unwell Frankie Dettori as a speaker at the Leaders In Racing conference.
"I feel great. I feel as fit as ever and I'm enjoying it, but I'm not getting the same rides as I used to.
"I've had a great career, I've enjoyed it, and I wouldn't like to go out without riding in the big races.
"If it continues to go downhill, I wouldn't stick around."
Asked whether training would be an option in the future, Fallon said: "I don't know. I would like to train. I thought for a long time I wouldn't want to because I wouldn't enjoy it."
He has four rides at Saturday's Newmarket meeting but does not have a mount in the two Group One races, the Dewhurst and Middle Park Stakes.
Fallon has twice been suspended for testing positive to prohibited substances and has also come back from bans resulting from charges of race fixing for which he was found not guilty.
