The Marlborough Horse Trials began under a charter with the Rosaryville Conservancy in 1992. Today, we continue our partnership with the conservancy to maintain the beauty of Rosaryville State Park and continue to provide equestrians with a first-class event each year over rolling and wooded terrain.
We also host other events throughout the year, such as our ever popular Jumper Derby to prepare riders for spring events and give folks a chance to compete in a fun and relaxed atmosphere.
