Born in Cambridge on June 17, 1999, Cieren Fallon is, of course, the son of six-time British Champion Jockey Kieren Fallon, who rode 2,253 winners before his retirement from the saddle in July 2016. Fallon Jnr. took his first ride on Rhigolter Rose, trained by William Haggas, in an apprentice handicap at Thirsk on August 31, 2018, finishing second, and opened his account, at just the third time of asking, on Plucky Dip, trained by John Ryan, in a similar contest at Leicester on September 24, 2018.
A graduate of the British Racing School in Newmarket, Fallon rode four winners in all in the closing weeks of the 2018 season but, under the tutelage of Haggas, increased his seasonal tally to 62 winners in 2019. He thus became British Champion Apprentice a little over two years after first sitting on a horse, for all that Haggas supplied just one of the 50 winners he rode in the qualifying period between May and October to take the apprentices’ title. In 2020, Fallon again rode 62 winners, including 43 during the Apprentice Jockeys’ Championship, which were sufficient to retain the title. He thus repeated the achievement of Gary Bardwell, who won back-to-back apprentice titles in 1987 and 1988.
On July 11, 2020, Fallon recorded his first Group 1 win on Oxted, trained by Roger Teal, in the July Cup at Newmarket. The following month, he was recruited by Qatar Racing, under the auspices of Sheikh Fahad bin Abdullah Al-Thani, to ride as second jockey, behind Oisin Murphy. Reflecting on his achievements, Fallon said, “Winning the July Cup with Oxted is obviously the greatest highlight of my year and a memorable day. It’s been an amazing two years really, but I don’t want to be overlooked as an apprentice anymore…” David Redvers, Racing and Bloodstock Manager for Sheikh Al-Thani, said of him, “He [Fallon] has an incredibly calm demeanour for his age, an intuitive riding style and is very level-headed.”
Having ridden out his claim on Twilight Song, trained by Ian Williams, at Salisbury on August 21, 2020, Fallon rode 84 winners in his first season as a fully-fledged professional in 2021, including his second Group 1 win, again on Oxted, in the King’s Stand Stakes at Royal Ascot. On July 1, 2024, he broke his back when unseated by his mount, Nanna Western, at Windsor, but recovered sufficiently to record a third Group 1 win, on Montassib, trained by Haggas,in the Haydock Sprint Cup later in the season.
