This is a terrific helmet-cam of the Olympic-class Rolex CCI 4-star Three Day Event here at the Kentucky Horse Park this past April.
This features Irish-bred ex-race horse "Running Order" at his first 4-star, ridden by Doug Payne. Narration added afterwards. They finished 18th.
Flat racing helmet-cams are pretty cool, but add huge fences, banks, etc. to galloping and you really have something
