TT star Guy Martin, alongside endurance mountain biker Jason Miles, is taking on the challenge of riding the UK's two coast-to-coast routes, as well as every mountain biking '7stanes' red route along the way.
Across the route from Scotland to Northern Ireland, Guy and Jason will be joined by the friends of Michael Bonney, a Penrith man who was paralysed following a mountain bike accident.
All funds raised through the adventure will go the 'Ride for Michael Trust', which aims to provide a special 'Functional Electrical Stimulation' bike which Michael will be able to pedal.
A donation page for the Ride for Michael Trust explains Michael's story:
