Stuart Walker

The charity challenger who aims to cover the length of the British Isles using only muscle power starts his quest tomorrow.

Stuart Walker, of West Yorkshire, will set off from the Western Rocks at the southern end of the Isles of Scilly to paddle, run, row and cycle the 2,250km (1,400 miles) from South to North, hoping to end his journey four weeks later at Out Stack, beyond Unst in Shetland.

By Monday, he aims to be on the mainland in Cornwall before starting his journey via the Brecon Beacons, Snowdonia, the Peak District, Yorkshire Dales, Lake District, the Borders, Glencoe, Lochaber, the Great Glen and John O’Groats before taking to the sea again for his final leg.

He hopes to raise cash for Avert Aids, Water for Kids and the NSPCC.

The Pudsey Pacers member is a seasoned fellrunner and adventure racer and in May completed the 100km (62-mile) Fellsman in 16hrs 21mins.

His journey is due to end on 17 July. Sir Ranulph Fiennes, who recently summited Everest at his third attempt, gave Stuart his backing, saying: “I wish Stuart all the best with his British Isles Challenge journey and fundraising efforts.

“It may not be an expedition to the ends of the earth, but the venture brings its own very real challenges, and will certainly test him to the limits. I would urge anyone to support the trip as much as possible.”

Stuart hopes to update his blog as he wends his way up Britain.
