Two members of Royston Runners are taking on the challenge of running from Lands End to John O'Groats to raise money for charity.

Men's captain Liam Butler and coach Grant Stefan Chapman will start the run on Saturday, July 24 and aim to cover 1,100 miles and 90,000 feet of ascent over 31 days - averaging 38 miles a day.

The duo, who are being supported by their fellow Royston Runners, have so far raised more than £500 for the Essex & Herts Air Ambulance Service, which is the club's charity.
