2000s
The 2000s began with the purchase of the Thoroughbred Center training facility located in northeast Lexington, which is still owned by Keeneland. The first level of the Clubhouse was enclosed in 2000, and a new slate floor and brick pavers were installed along with mutuel windows, concession stands, and closed-circuit televisions. The new Keeneland Library building opened in 2002 and the Library also received a Special Eclipse Award the same year for its contributions to preserving the history of Thoroughbred racing.
The surface of the training track was replaced with Polytrack racing surface in 2004 and two years later, the main track was also replaced with Polytrack, making Keeneland the third racetrack in North America to adopt the new surface. The turns were also widened, and Trakus video race technology, which tracks horses via sensor chips in saddle cloths and atennas around the track, was introduced. Keeneland was the first racetrack in the United States to offer this technology, which was in use until 2023. The tote board was also replaced with a state-of-the-art LED version. Keene Place, the original 1805 home of a branch of the Keene family, was purchased by Keeneland in 2003 and reopened after renovations in 2009. In April of 2009, Keeneland became the second racetrack accredited by the National Thoroughbred Racing Associations' Safety and Integrity Alliance.
The Sales Pavilion saw a number of changes throughout the decade beginning with a 13,000 square foot covered exterior show ring that opened during the September Yearling Sale in 2000. An expansion for the Repository for X-rays, new and larger conference rooms, a kitchen, additional dining areas, a bar area, renovated press area, and a new business center followed in 2005. Additionally, hi-speed wireless access, an updated sound system, and bid board systems were added throughout the building.
