Phillips was a reserve member of the British equestrian team for the 1968 Summer Olympics. He was an integral part of the British three-day event teams that secured a world title in 1970, a European title in 1971, and an Olympic gold medal at the 1972 Summer Olympics in Munich. Individually, he finished in 35th place in the 1972 event. At the 1988 Summer Olympics in Seoul, Phillips earned a silver medal with the British team, although his horse sustained a pulled muscle and was unable to complete the individual three-day event.
He achieved remarkable success at the prestigious Badminton Horse Trials, becoming a four-time champion. He won in 1971 and 1972 riding Great Ovation, in 1974 on Colombus, and in 1981 on Lincoln. It was through his involvement in equestrian activities that he met Princess Anne, the only daughter of Queen Elizabeth II and Prince Philip, Duke of Edinburgh, whom he subsequently married.

5. Personal life
5.1. Marriage to Princess Anne

Mark Phillips first met his future wife, Princess Anne, at a party for horse enthusiasts in 1968. They married on 14 November 1973, at Westminster Abbey. The couple had two children: Peter Phillips (born 1977) and Zara Tindall (born 1981). As a wedding present, Queen Elizabeth II purchased Gatcombe Park, near Minchinhampton, for the couple. Phillips reportedly declined a peerage from the Queen, which allowed his children to use courtesy titles rather than being styled as "His/Her Royal Highness" or "Prince/Princess" under the terms of George V's 1917 letters patent. Had Phillips held a peerage, his children with Princess Anne would have been entitled to be styled as "The Honourable", or as "Lord" or "Lady", depending on the peerage created.
In August 1989, Princess Anne and Phillips announced their intention to separate, as their marriage had been under strain for several years. The couple had rarely been seen together in public, and both were romantically linked with other individuals. They initially stated there were no plans for divorce and continued to share custody of their children. Phillips also continued to work at the couple's estate at Gatcombe Park. They divorced on 23 April 1992.
Phillips' personal wealth is estimated to be around 15.00 M GBP to 20.00 M GBP. The settlement he received upon his divorce from Princess Anne was described as "modest" and reported to be around 3.00 M USD. On 19 September 2022, Phillips was present at the committal service at St George's Chapel for his former mother-in-law, Elizabeth II.
5.2. Marriage to Sandy Pflueger
On 1 February 1997, Mark Phillips married Sandy Pflueger, an American Olympic dressage rider. Their daughter, Stephanie, was born on 2 October 1997. She grew up at Aston Farm, Gatcombe Park, in close proximity to the family of Princess Anne, and served as a bridesmaid at the wedding of her half-sister, Zara Tindall. In 2000, Phillips was appointed an Honorary Liveryman of the Worshipful Company of Farmers.

9. Assessment
Mark Phillips is widely recognized as a highly accomplished figure in the world of equestrianism. His career as an Olympic gold and silver medalist in eventing firmly established his reputation as a top-tier athlete. Beyond his competitive achievements, his contributions to the sport extend to his influential role as a cross-country course designer, which has shaped numerous major events, including the Red Hills Horse Trials. His continued presence as a columnist for Horse & Hound magazine and his leadership as Chef d'EquipeFrench for the United States Eventing Team underscore his enduring commitment and expertise in equestrian circles. His former marriage to Anne, Princess Royal, brought him into the public eye beyond the sporting arena, but he maintained a distinct identity rooted in his professional passion for horses. Phillips' legacy is primarily defined by his significant and sustained impact on equestrian sport, both as a competitor and as a guiding force in its development.
