Computer consultant Mark Bellinger hopes to set a world record by playing squash for 50 hours.

He will raise cash for charity during the attempt at the end of August, which will involve playing about 40,000 strokes.

Mark, from Haywards Health, has already played a 24-hour marathon without suffering any injury or a single blister.

If he can play for twice as long and keep standing, the feet will be most remarkable.
