A Nottingham-based estate agent is to walk across the Sahara desert for charity.Gordon Brown (pictured), a director of local estate agency Freckleton Brown and a franchisee of national mortgage broker Mortgage Talk, is striding out in aid of the Macmillan Cancer Relief charity from February 18 to 26 next year. He will be joined in his seven-day, 70 mile quest by his friend, 42 year old Trevor Parkinson, a former leukaemia sufferer. Brown has secured pledges totalling over £1,700 and is hopeful of smashing his provisional £2,000 target. The challenge has a personal note for the 44 year old as his mother died of cancer in 1997 and his father was recently diagnosed with the disease. Brown aims to walk 10 miles each day in the blistering heat and camp outdoors in freezing overnight temperatures.
