David Harrison with Her Majesty Queen Elizabeth II after their triumph in the 1992 Royal Hunt Cup
In 1997, he rode Single Empire to victory in the Derby Italiano trained by Peter Chapple-Hyam. Other notable group winners during his career include Penny Drops and Mongol Warrior, both trained by Lord Huntingdon, the latter becoming the first British-trained winner of the Swiss Derby. He rode many other winners worldwide with the majority coming in the UK and Hong Kong where he was a retained jockey to trainers James Fanshawe and Brian Kan.[2]
Harrison's career ended prematurely after he damaged his spinal cord when he fell from the racehorse, My Chief, in a race at Sha Tin Racecourse, Hong Kong, on 30 May 2001.[3] My Chief clipped the heels of another horse and took a heavy fall.[2]
After his accident, Harrison relocated to Andalucia and became an agent for other jockeys.[1]
