The Equestrian competition at the 2012 London Olympics included three activities: dressage, eventing, and show jumping. Dressage tests the horse and rider's memorization and performance of movements at different paces and transitions. Eventing involves navigating cross-country courses with jumps and hazards over hilly terrain and water features. Show jumping challenges the horse and rider's ability to clear obstacle poles without faults in the fastest time. Great Britain medaled most overall in the equestrian competition.
