Eventing could be termed an "equestrian triathlon." It involves working with a horse both on the flat and over fences. The three phases are: dressage, endurance (or cross-country), and show jumping. Over the centuries it has developed from the test of the ideal military charger. Eventing has now evolved into an exciting sport attracting interest from all levels of sports enthusiasts, from weekend hobby riders to professional international stars.

With its variation in levels and difficulty and wide range of competitions available all across the country, Eventing is a sport which provides competitive and recreational opportunities for people of all ages and backgrounds. Today, the sport is most known for its cross-country phase where horse and rider gallop over an outside course of solid obstacles which the horse has never seen before. At the uppermost level of competition, Olympic or World Championship, the endurance day consists of Phase A-Roads and Tracks, approximately three and a half miles of walk and trot as a warm-up; Phase B-Steeplechase, approximately two and one-eighth miles at a gallop over approximately eight steeplechase fences; Phase C-Roads and Tracks, approximately seven miles of walk and trot as a cool down from steeplechase, and Phase D-Cross-country, approximately five miles at a gallop over a maximum of 45 obstacles that can be up to four feet high and ten feet wide (at the base). The horse's speed on this phase is over 20 miles per hour.
