Blind adventurer Miles Hilton-Barber has climbed both Mount Kilimanjaro and Mont Blanc, completed an 11-day marathon across China and crossed Qatar's desert on foot without any sleep — all within the last seven years.

The 58-year-old Zimbabwe native, who began losing his sight due to a hereditary disease when he was 21, has also completed a half marathon in snow-covered Siberia and holds the world record for being the first blind person to fly across the English Channel in a microlight aircraft.

"I'm just an ordinary man," Hilton-Barber, who was in Japan earlier this month to promote Seeing is Believing, a campaign to aid curable blindness, said in humbly describing himself.
