The $60,000 Adequan USEA Advanced Final is the premier championship division held at the AEC, showcasing the top national level of the sport in the United States. This division features the nation’s elite horse-and-rider combinations competing at the Advanced level, the highest recognized level of national eventing competition. The 2025 Adequan Advanced Final will take place Aug. 26–31 at Galway Downs in Temecula, California. In 2026, the Adequan USEA Advanced Final will return to the Kentucky Horse Park in Lexington, Kentucky, for a three-year rotation.
