Wanyoike is one of the world's fastest runners. While still a child he was already being groomed to join an elite corps of athletes in a country that is known for producing more world-class middle-distance runners over the last twenty years than any other country on earth. He excelled at the 5,000 and 10,000-meter distances.

Wanyoike became almost completely blind after suffering a stroke on May 1, 1995. "I went to bed a normal person, the following day I found myself in darkness." That night he lost 95% of his vision, and lost the rest gradually over the next few years. He was in despair. "I thought my life had come to an end."^[1]

His mother Grace brought him to the Kikuyu Eye Clinic (a nearby hospital supported by Christian Blind Mission International (CBMI), recognised as one of the best centers for the visually impaired in East Africa. Petra Verweyen, the chief of the Low Vision Project of the clinic, helped him to find his way back into life and arranged for him to learn to knit pullovers. With gratitude for the help he received at the project he promised himself he would help other blind people and teach them to become self-sufficient, as he had done. After winning his first gold medal in Sydney, Australia in 2000 at the Paralympic games, he has bought knitting machines through prize money and charitable donations from such international personalities as Arnold Schwarzenegger. He now employs other blind Kenyans and teaches them how to knit pullovers.

A blind runner is connected to a guide by a tether on the wrist, which the guide uses to subtly indicate, without breaking stride, when to turn, accelerate or avoid an obstacle, whether on the track or on the road, as in a marathon. Once Henry got used to working with guides, he quickly established himself as a world-class non-sighted runner, earning a spot on the Kenyan national squad for the 5000-meter race at the Sydney Paralympics in 2000. As he ran so quickly another problem emerged, that his guides could not keep up. Nevertheless, he not only won the gold medal but set a Paralympic record too. Now Wanyoike runs with his track guide and childhood friend, Joseph Kibunja.

Unlike most Kenyan athletes, who tend to concentrate on one or two events, Henry is among those very few who have ventured beyond. Over the last five years, he has won gold or silver medals in the marathon, half-marathon, 10 km road race, the 10,000 meters, 5,000 meters and the 1,500 meters. No other Kenyan athlete has ventured so widely and so successfully. His time of 2:31:31 at the Hamburg Marathon in 2005 still stands as the world record for blind runners.
