Wheelchair user pushing himself across Africa
Zackary Kimotho from Kenya has been a wheelchair user since he was shot in a car-jacking eight years ago.
While he is one of thousands of Kenyans with spinal injuries, there is currently no specialist care available in the country.
Now Zack is attempting to raise nearly £2m to build a Spinal Injury Rehabilitation Unit in Nairobi - the first in East Africa.
To do this he is pushing himself across Africa - from the Kenyan capital Nairobi to South Africa, where the nearest Spinal Unit is.
Matthew Pinsent met him as he approached the Kenya-Tanzania border. He had covered over 100 miles but still had more than 2,000 remaining.
