During four days of competition located in Kalispell Montana, thousands of spectators will see some of the finest riders in the world, as well as promising young competitors. Spectators come here to watch the horses and riders negotiate the complicated "questions" designed by Capt. Mark Phillips, U.S. Olympic Team coach. We continue to mark historic milestones as the largest equestrian triathlon in the U.S. and an important step to the 2012 London Olympics.
