A Yorkshire amputee has taken on a courageous run for charity.

Phil Sheridan is running from Ilkley along the Yorkshire Dales Long Distance Footpath to Windermere in the Lake District in just three days.

Phil runs using a prosthetic running blade, just like those used by Paralympians Oscar Pistorious and Jonnie Peacock, which was supplied by the prosthetics specialists PLSSteeper and Leeds Training Hospitals.

Thanks to the blade and his own grit and determination, Phil will run the 80 miles to raise money for MIND, Martin House Children's Hospice, Combat Stress and Survival International.

Phil lost his right leg in a biking accident in 2002.

After proving his fitness and taking delivery of the blade, he decided to tackle the run as a way of showing his appreciation for the help and support given by family, friends and medical practitioners over the years.

He also believes his challenge may provide inspiration to others who have been through a life-changing experience and who may be finding it difficult to adjust.

Phil said: "I can honestly say that from the support I've had from RSLSteeper, Leeds Teaching Hospitals and from my family and friends has been incredible, and completing this run is my way of showing them how grateful I am and that all of their efforts have been worthwhile."

Each of the stages will be longer than a marathon, taking on steep and rocky ascents, as well as grassy trails and bridleways.

Because of the terrain, Phil's blade has to be fitted with a trail running sole.

He said: "It will take me and the blade out of our comfort zones. I’'l be running alone so I have to make sure I'm up to the job as is the blade - it has to be in a perfect condition before I set off."

Phil would like to raise £20,000 for his chosen charities.
