David ‘Tids’ Tidball, Dan Thorogood and Felicity Elliott – all members of the Exmouth Beach Rescue Club – provided rescue cover in the first Olympic test event that was also part of the World Championship Series.
The Hyde Park challenge was made up of a 1500m swim, a 40km bike ride and a 10km run.
Volunteer lifeguard ‘Tids’ Tidball said: “The many years of commitment shown by our volunteers has been justly rewarded by our selection as part of the Olympic 2012 water safety team.
“This role is a great honour that comes with great responsibility.
“The men’s event on Sunday was watched live on BBC2 and across the world by millions.
“If anything goes wrong with an athlete during a competition, it can be life-threatening and the team have to be the best in their field.
“Lifeguards from Exmouth and two other Devon clubs of Dawlish Warren and Saunton are the only clubs to have been chosen.
“We are proud to be recognised for our specialist ability.
“We are part of an elite group of volunteers who provide safety to water users across Devon on a daily basis, and to many thousands of amateur competitors at national and regional events.
“But the 2012 Olympics is the pinnacle of all these events.”
