Zachary Kimotho lost the use of his legs in 2004 when a gunman shot him in an attempted car-hijacking.
He is now wheeling himself 4,000km away from Kenya, to the nearest spinal rehabilitation clinic, in Cape Town.
Kimotho hopes to raise 250 million Kenyan shillings to build a rehabilitation centre in Kenya along the way. He also hopes to draw attention to the way disabled people are treated right across the continent.
