He is currently the first choice jockey for Aidan O'Brien's Ballydoyle operation, a role in which he mainly rides horses owned by Coolmore Stud.

[2] Charlie was also a second-hand car salesman, and many stories have circulated about his dual career, including how he swapped three truck tyres in exchange for a filly,[2] and how he started training when he accidentally bought a horse by raising his hand at auction.

However, he didn't enjoy cross country and showjumping, finding it a "bit tame" when he wanted to be doing competitive racing instead.

[4] His first major victory came for a different trainer, though, when he won the 2002 Cesarewitch Handicap for Martin Pipe on Miss Fara on 19 October 2002.

He got his first black type victory later that same year when winning the Listed Jebel Ali Stakes in the United Arab Emirates shortly after Christmas 2002.

[6] Increasingly, Moore rode for Sir Michael Stoute, sharing those duties with Kerrin McEvoy, Mick Kinane and others after Kieren Fallon quit as stable jockey to ride for Aidan O'Brien.

[2] In that year, Stoute horses gave him 47 of his 126 wins,[dubious – discuss] overtaking Hannon (33 winners) as his primary stable.

[5] These efforts were rewarded when he was offered the job as stable jockey at the end of the 2007 season, while he was in Tokyo, riding Papal Bull in the Japan Cup.

Hannon meanwhile would make more use of his son-in-law Richard Hughes (jockey), after his retainer with Khaled Abdullah came to an end.

In April 2009, he rode winners at Sandown Park, Sha Tin in Hong Kong, and Windsor on consecutive days, the 36-hour trip to the Far East winning him nearly £50,000 after he won the Queen Elizabeth II Cup on Presvis, trained by Luca Cumani.

A broken wrist cost him another chance at the jockeys' title, but he was already being spoken of as an all-time great by some commentators.

He rode for many of the Manchester United team including Michael Owen, Paul Scholes, Ashley Cole and manager Alex Ferguson.

[3] Moore also rode the Queen's Carlton House to victory in the Dante Stakes at York Racecourse and then to a close 3rd in the Epsom Derby.

They negotiated a compromise that allowed Moore to live in England, while riding for O'Brien in Ireland at the major meetings.

[12] By 2015, Joseph O'Brien, at nearly 6 ft tall, was struggling to make the weight to ride in the major races and his father Aidan needed a replacement.

"[11] By the end of the 2017 season, Moore had won over 2,000 races in Britain, the third most of all active jockeys, behind only Frankie Dettori and Joe Fanning, both of whom had been riding for a decade longer.

[13] To date, Moore has ridden three Derby winners for O'Brien - Ruler of the World in 2013 and then successive victories on Auguste Rodin and City of Troy in 2023 and 2024.
