Grand Slam of Eventing

The Grand Slam of Eventing, sponsored by Rolex, consists of three of the top CCI5*-L (previously CCI4*, due to a rating change effective January 1, 2019. Note that the nature of the competitions remains the same regardless of the change in name) equestrian eventing competitions in the world. Pippa Funnell in 2003 and Michael Jung in 2016, are the only riders to have achieved the Grand Slam since its inception in 1999. To win the Grand Slam, a rider must consecutively win all three events, although they are permitted to ride different horses in each competition. This is especially important, since the Badminton Horse Trials is only one week after Kentucky, and the horse would not have sufficient time to recover between the two competitions, especially since they would have to be flown overseas in that time.

The three events that make up the Grand Slam are:
 * Land Rover Kentucky Three-Day Event in Lexington, Kentucky, United States
 * Mitsubishi Motors Badminton Horse Trials in Gloucestershire, England
 * Land Rover Burghley Horse Trials near Stamford, Lincolnshire, England

Winners receive an extra $350,000, in addition to their winnings from each event.

Rolex
Having picked up the Grand Slam concept, which was originally launched by the three events acting in concert, the company have since established themselves as a leading sponsor within Three Day Eventing. Furthermore, they were title sponsors of the Rolex Kentucky Horse Trials until they abandoned eventing title sponsorship across the globe and dropped the sponsorship. The Rolex Kentucky Horse Trials is now the Land Rover Kentucky Three Day Event, since Land Rover picked up the sponsorship. Rolex was the title sponsor of the event from 1981 to 2017. Rolex remains the official timepiece of the event.
