Staffordshire Moorlands AC runners Jason Burgess and James Wood combined to secure a sensational team victory for Great Britain at the 2014 Mud-Run World Championships in the US.
Sam Lucking (Staffs Moorlands AC) and Mark Dalkins (Cheadle Running Club) made it a double medal haul for GB in Savannah, Georgia, by finishing third.
Burgess, Wood and Lucking made the trip across the Atlantic after winning the team competition in last year's UK version of the race.
Dalkins was invited to joined them in the GB squad as the 2013 individual race winner.
An elated Burgess said afterwards: "It was a great honour to be asked to compete representing the UK in such a prestigious event.
"All of the lads did the UK proud and to have three of the four athletes selected to compete being current members of SMAC shows the talent and versatility we have in the club.
"I would like to thank JCB for a well-organised event and for their hospitality during the team's four-day stay in America."
Lucking took advantage of his GB appearance to raise £215 for his nominated charity, the Rheumatoid Arthritis Society.
Staffordshire Moorlands AC coach Dave Owen said: "To have local athletes claim first and third at world level is very exciting for local sport and recognition of our quality athletes.
"I am privileged and fortunate enough to coach Jason, Sam and James, and I am immensely proud to see their hard work rewarded with a world title in such a highly-regarded event.
"It should be noted that some 1,600 athletes took part in this event. The top three finishes attained by SMAC runners is testament to the hard work and training put in by these lads, week after week.
"It is a just reward for the many sacrifices both they and their families face to attain a level of fitness to compete for their country at such a quality event."
The next JCB mud run is being held in Uttoxeter this Saturday.
