After months of qualifying shows, the fall indoor season is officially underway. It kicked off Friday, Sept. 27, with Capital Challenge‘s equitation weekend, but there’s still plenty happening. Riders have converged in Upper Marlboro, Maryland, for the chance to vie for glory in the World Champion Hunter Rider challenge classes. Competition continues through Sunday, Oct. 6.

Some of the biggest classes of the show run Wednesday and Friday nights when professionals go head-to-head for bragging rights (and money), first in the WCHR Professional and Developing Pro Challenge classes on Wednesday, then in the WCHR Pro Finals—the class where pros take turns riding each others’ other horses.

But the pros aren’t the only ones under the spotlight. There are challenge classes for everyone from children’s hunters to the 3’6″ divisions. You can read about all of the WCHR classes offered here.
