At age nine, David was watching the 1976 Olympic Games and dreamed of becoming an Olympian. He began his journey as a bicycle motocross racer. Over the next four years he earned more than 100 trophies and toured Southern California on a bicycle motocross stunt/freestyle team.
At 14, he began cycling, and during his first year he won both the Road and Track National Championships. The following year he was invited to live and at the U.S. Olympic Training Center in Colorado Springs, Colorado.
Brinton ultimately competed in seven World Championships, won gold and silver medals at the Pan American Games, set four national records and competed in the 1988 Olympic Games in Seoul.
Following his cycling career, David became a Hollywood stuntman and can be seen jumping cars, crashing his bicycle and doing other stunts in more than 120 movies, TV shows and commercials.
Recently, he once again began competing internationally and has earned four Master World Track Championship titles and set three Master World Records in 2013-2015. Today, David is still competing and is a successful cycling coach and public speaker.
