Rafalca, the horse co-owned by Ann Romney, made her Olympic debut on Thursday.
The horse scored 70.243 with rider Jan Ebeling in dressage, which involves horses carrying out controlled movements and has been compared to ballet.
Mrs. Romney told The Associated Press the horse's performance “thrilled me to death.†She won't know until Friday if her horse has qualified for the next stage of the competition on Aug. 7.
