At a young age, Lex Gillette lost his sight following several surgeries for detached retinas. But with support from friends, family members and coach Brian Whitmer, Gillette overcame that to become the Paralympics world record holder in the long jump at 6.73 meters, or about 22 feet. He’s participated in the past three Paralympic Games, including the most recent in London, England, each time earning a silver medal for the long jump.Since losing his sight, Gillette has lived by the mantra, “no need for sight when you have a vision.”
