Professional Experience
David comes from one of Irish racing's best-known families. The son of trainer Tom Mullins and grandson of Paddy Mullins, he rode extensively for his uncle, multiple Irish champion trainer Willie Mullins.
His first Grade 1 victory arrived aboard Nichols Canyon in the 2015 Morgiana Hurdle, where the pair inflicted a first career defeat on the previously unbeaten Champion Hurdle winner Faugheen.
Just months later, David produced the defining ride of his career. On his first Grand National appearance, the 19-year-old partnered Mouse Morris-trained Rule The World to victory at Aintree, patiently guiding the 33/1 outsider to a six-length success.
Further Grade 1 victories followed aboard leading horses including Faugheen, Al Boum Photo, Bellshill and Kemboy. His major wins included the Champion Stayers Hurdle, Ryanair Gold Cup, Punchestown Gold Cup and Savills Chase.
David retired from race riding in 2021 at just 24, finishing his career with nine Grade 1 victories and 40 Graded wins.
