I caught this great video on EventingNation.com, which is a virtual coursewalk of the international three-day event Badminton. Held annually since 1949, the show takes place in the event park of Badminton House in Gloucestershire, England.
The first video follows a bird-eye view of the course route, with the available alternates.
This additional video is the official course preview that is available on the Badminton website. The narrator Hugh Thomas explains each fence and they approach each fence on foot, which gives us an idea of how big and wide these fences really are!
