"[Chris] and I trained together, went to school together and even took the same major," Horton said. "If not for gymnastics, we would probably have to do something as equally active. We are kind of adrenaline junkies. We like to ride fast motorcycles and drive fast cars."
According to his USA Olympic team profile, Horton, 26, was a "wild child," stating "I once climbed a pole in the middle of Target all the way to the ceiling. I used to do back flips on my parents bed, and I rode a garage door to the top when I was three years old."
Horton first competed at the Olympic trials in 2004. As a college freshman, he finished 12th before returning to his training under coach Mark Williams. He competed for the University of Oklahoma, where he graduated in 2008.
That same year, Horton participated in the Olympic trials for a second time. He traveled to Beijing with the U.S. men's Olympic gymnastics team when team leaders Paul Hamm and Morgan Hamm suffered injuries. Alternates were brought in, and the team pressed on to receive the bronze medal. As the team's top performer, Horton left with a silver medal in high bar, which fueled his desire to continue his training as an Olympian.
