As might be expected, Arabians and part-Arabians were by far the largest percentage of breeds competing in US endurance riding in 2014.
Pure-bred Arabians made up 61.94%, while half-Arabians and Arabian crosses were 16.65% of the total.
The Mustang is the second-most pure breed in the sport, making up 1.74%.
Exhibiting the variance of mounts in endurance, one might run into some rare breeds on the trails, including Colorado Ranger, Mangalarga Marchador, Blazer, Florida Cracker Horse, Gypsy Vanner, McCurdy Plantation Horse, Moyle, Oldenburg, and Spotted Mountain Horse.
