As the daughter of an Olympic eventer, Olivia Dutton grew up immersed in the sport of eventing. Now ranked No. 25 in the FEI Eventing U25 World Rankings, she has built an impressive résumé through consistent performances at the upper levels and successful partnerships with horses including Sea of Clouds and Jewelent.  Throughout her career, Dutton has compiled an impressive list of accomplishments, including a team silver medal at the 2025 Bicton CCIO4*NC-S, a NAJYRC CCIOY3*S Team Gold Medal in 2018, and a third-place finish in the $20,000 Indoor Eventing Challenge at Toronto's Royal Agricultural Winter Fair in 2023. Riding the 15-year-old Thoroughbred Sea of Clouds, Dutton has become a familiar face at the Kentucky Three-Day Event, making three consecutive appearances in the Cosequin Lexington CCI4* from 2024–2026. Together, the pair has continued to climb the international ranks, contesting multiple CCI4* events, including Bromont International and Military Boekelo-Enschede, before capturing a standout CCI4*-S victory at the Morven Park Fall International and Horse Trials in 2025.
