Claire Lomas is training today for her big challenge at the end of April when she hand cycles from Nottingham to London. That is the equivalent of a marathon a day over three weeks.
Claire was paralysed from the waist down when she was injured in a horse riding accident. Last year she became the first person to complete the London Marathon using a robotic walking suit in a time of 17 days.
This year Claire will be cycling down to London with 60 other riders in a specially designed wheelchair.
