Castlefield Conelious, nicknamed “Collin,” competed as a young horse in Europe with Great Britain’s Laura Kennedy before joining Philip Rüping’s (GER) string. In mid-2023, he came to the U.S. to partner with jumping athlete Kaitlin Campbell. In the fall of that year, the pair were part of the winning team at Major League Show Jumping CSI5* in Greenwich, Conn. From there, they went on to a successful 2024 winter season that included a second-place finish in the Desert International Horse Park 1.55m Grand Prix CSI4*. 

In the summer of 2024, Collin and Campbell earned an impressive second place in the Odium Brown CSI4* Grand Prix in Vancouver, Canada. They finished in the top ten individually and were part of the winning team in the $300,000 CSI5* MLSJ Team Competition in Traverse City, Mich., in September. In 2025, the pair represented the U.S. as part of the team for the Longines League of Nations CSIO5* competition in Abu Dhabi (UAE).
