A man from Merthyr climbed Africa's highest peak to raise money for charity. Geraint Williams was diagnosed with Friedreich's ataxia - a rare nerve disorder - 11 years ago.
He used a special wheelchair known as a 'mountain trike' - a cross between a wheelchair and a mountain bike - to complete the climb up Mount Kilimanjaro a few months ago.
Around 10,000 people in the UK have Friedreich's ataxia - with 500 of them being children.
The charity Ataxia UK says the condition is so rare it's often not recognised or detected and there is no cure.
The disorder steals a person's central ability to communicate and walk and progresses quickly.
