In the years since, Phillips suffered a dry spell, only to come charging back on a new horse last year. Just months ago, she was considered a long shot for the Olympic team.
Phillips comes from an Olympian and equestrian family. Her mother, the Princess Royal, competed at the Montreal Olympics in 1976, while her father, Mark Phillips, won team gold at the Munich Games in 1972 and team silver in 1988 at the games in Seoul.
The equestrian events will be held at London's Greenwich Park. The Olympic Games run from July 27-Aug. 12.
