HM Naval Base Clyde raise thousands for charity with 100-hour challenge People at HM Naval Base Clyde recently raised thousands of pounds for charity after an epic 100-hour non-stop cardiovascular challenge. A total of 100 service and civilian personnel took it in turns to run, cycle or cross train continuously at the Naval Base's Neptune Building. Starting the event was Commodore Mark Gayfer, Naval Base Commander Clyde, the first of a number of volunteers who maintained the challenge until midday on Friday, March 24. Captain of HMS Neptune, Captain Craig Mearns, who participated in the challenge said: "This was a tremendous event and a great example of how the Naval Base can come together for a fantastic cause. "Thanks to the sweat and hard work of everyone involved we have raised an amazing £2,369.09 for the Royal Navy and Royal Marines Charity." The event was organised by HMS Neptune Field Gun Crew and the Naval Base's Sportsdrome and was run in the honour of the upcoming 100th Army v Navy Rugby match which will be held at Twickenham on April 27 this year and also the Brickwoods Field Gun Competition. During the 100 hours, some 2,277.9 km were covered with donations collected from passers-by throughout. Challenge yourself for Twickenham100!
