A HARDY father and son will walk for 100 miles without any sleep in aid of two charities.
Robert and Andy Powell will tackle the South Downs Way, walking from Winchester, in Hampshire, past Brighton and ending in Eastbourne, in East Sussex – the equivalent of four marathons.
Robert, 28, and Andy, 51, will set off at 6pm today and hope to complete the gruelling challenge by Saturday lunchtime.
The determined pair are taking part in the trek in aid of Macmillan Cancer Support and the Great North Air Ambulance.
Former Brierton School and Hartlepool College of Further Education student Robert left Hartlepool 10 years ago to go to university in London.
He now lives in London and works in marketing for CMS Cameron McKenna lawyers, but his mum, Linda Powell, 51, still lives in the Naisberry Park area of Hartlepool.
Andy, who has a partner called Valerie Witham, left the town around 15 years ago and now lives in Greysouthen, in Cumbria.
Robert, who visits his Hartlepool relatives three or four times a year, says he has been preparing for the trek by running and playing football and did a 40-mile walk recently.
His dad has been taking 20-mile walks around the Lakes.
The pair hope to get through the 42 hours by taking energy drinks and nutrition bars with them and eating tuna and pasta.
They will have 15-minute breaks every 12 to 15 miles.
