Jumbo Games MD Gray Richmond raised £2,000 at the London Marathon.
He undertook the challenge on Sunday, April 21st to raise money and awareness for the MS Trust.
Richmond said: "It was definitely gruelling, but the incredible atmosphere and support of friends, family and total strangers just carries you along through those tough moments.
"It was an amazing experience and worth all the pain and the rather unpleasant winter training. Would I do it again? Ask me next week."
The 26.2 mile challenge was faced by thousands of fundraisers, amateur runners and professional athletes, including Olympic Gold medalist Mo Farah.
It was the 33rd annual London Marathon.
