About Millbrook Horse Trials

The Millbrook Horse Trials (MHT), a recognized United States Eventing Association (USEA) Event, is an important part of a long equestrian tradition in Dutchess County. Recognized among the region's most prestigious annual sporting events, it attracts world-class competitors from throughout the United States and brings some 400 riders and their support staff into the local community each year. MHT is the largest event in the northeast and the only one with an advanced division. US Olympic team riders regularly compete their upper level horses at Millbrook to warm up for the top international competitions.

Considered the triathlon of the equestrian world, Eventing is a rapidly growing sport. It includes three equine disciplines: Dressage, Cross Country and Stadium Jumping. MHT provides all recognized levels of competition from USEA Beginner Novice to Advanced level.

The Millbrook Horse Trials' success in attracting over 3,000 competitors and spectators is a product of its reputation for presenting a well-organized competitive environment, with expert F.E.I.-designed courses, in a beautifully maintained open landscape.
