Paralympic Dressage Primer  by Ellie Brimmer I am a High Performance Para-Equestrian Dressage competitor, and I will be blogging for Sidelines in London this year, with photography support from Lindsay McCall, head of United States Para-Equestrian Association (USPEA) media relations and the Paralympic Equestrian Media Coordinator. The Olympic competition has officially completed, but you do not have to wait long to watch world-class equestrian competition.
