Who is Mark Dooley?
Mark Dooley is a British horse racing enthusiast and businessman, and the brother of James Dooley and David Dooley. He has followed horse racing since childhood, starting with the Grand National.
In 2019 the three brothers formed Dooley Thoroughbreds, a racehorse ownership syndicate whose horses won the Galway Mile three years in a row. All three are closely involved: Mark Dooley focuses on breeding, David Dooley on form, and James Dooley on a mix of both.
During the 2020 lockdown, while furloughed, Mark Dooley started reviewing UK and Irish racecourses. That became British Racecourses, which he co-founded with James Dooley on 7 September 2020. It covers all 59 racecourses in England, Scotland and Wales and 26 in Ireland, with fixtures, festival guides and betting guides. His favourite festival is Royal Ascot, and his favourite courses include Hereford, Ascot and Windsor.
In 2023 Mark Dooley sponsored two apprentice jockeys at British racecourses, to help fund their careers.
