Pippa Funnell, a prominent British equestrian, made history by becoming the first woman to win eventing's Grand Slam. This Grand Slam consists of winning three of the most prestigious competitions in the sport—Kentucky Three-Day Event in the USA, Badminton Horse Trials in the UK, and Burghley Horse Trials in the UK—all within the same calendar year. This feat is incredibly challenging due to the varying courses, the physical demands on both horse and rider, and the level of competition faced at each event. Reflecting on her achievement, Funnell said, "Achieving the Grand Slam with Primmore's Pride was a dream come true. He was simply outstanding. There wasn’t a day when I didn’t feel privileged to ride such a magnificent horse. He gave his heart every single time we went out there."

Funnell achieved this remarkable accomplishment in 2003. She rode Primmore's Pride, a horse that became almost synonymous with her career, to clinch victories at all three events. Primmore's Pride, known for his consistency, bravery, and strong partnership with Funnell, was key to her success during this period. Together, they not only completed the Grand Slam but also contributed significantly to her international success, including team and individual medals at major championships.

Pippa Funnell's achievements with Primmore's Pride helped elevate her status in the sport, showcasing her skill, determination, and the deep bond she formed with her equine partners. This milestone remains a significant highlight in the history of equestrian sports, underscoring the extraordinary accomplishments possible through exceptional human-animal partnerships.
