Riding a bike from Land's End to John O'Groats in 10 days would be enough of a fundraising challenge in itself.
But not for Norman Renshaw. The InTuition boss is also planning to grow a moustache en route, as he pedals to raise money for charity.
"Moustache growing is apparently obligatory when raising money for prostate cancer," jokes Norman, who only started cycling for his 847-mile ride in December and is now doing about 70 miles a week.
Norman, 49, who is cycling with a couple of friends, will have to do about 90 miles a day to meet his target. "I'm hoping for south-westerly winds and really hoping it doesn't rain," he says. "I'm also looking forward to a couple of whiskies when we finish in John O'Groats - I've got family there and I am hoping they'll turn out."
He promises that his "midlife crisis" ride, which begins on May 3, will be his one and only charity appeal. His target is to raise £3,000 for The Prostate Cancer Charity, which supports research.
