The 2010 FEI World Equestrian Games in Lexington, Kentucky marked a series of firsts in WEG history: the first time WEG were held outside Europe; the first time that championships for eight FEI disciplines were held at one location (the Kentucky Horse Park); and the first time WEG had a title sponsor (in this case the animal health and nutrition group corporation Alltech, headquartered in the nearby city of Nicholasville). Permanent upgrades added to the Kentucky Horse Park leading up to the event included the completion of a 6,000 seat, climate-controlled indoor arena and completion of a 7,500 seat outdoor stadium.
