In the fast and furious mixed relay, Stimpson put Britain with the leaders in the first leg, before Jonathan Brownlee was part of a breakaway in the second that ensured Britan of a medal.

Jenkins, the new women's world number one, then put in a killer third leg to give a 10-second lead to Alistair Brownlee, the number one man in the world, in the anchor position.

Brownlee then extended that further, handing Britain a time of one hour, 9min 29sec to win by 15 seconds from Switzerland, the 2009 and 2010 champions.

"Yesterday was a struggle and today was hard, but I didn't want to let the team down, and it's great to come away with two medals, but it's thanks to the teammates," said Alistair Brownlee, who had finished third in the sprint event behind brother Jonathan and Spain's Javier Gomez.

Stimpson also praised her team.

"I mean, who can you get better than these guys?" she said.

"They are the world's best and I got to be in a team with them so it's pretty awesome."

An excellent run from Sven Riederer put Switzerland into silver, keeping the home team's record as the only country to claim a medal at each edition of the re-vamped Team Triathlon World Championships.

Riederer said it was an amazing achievement for his team, including Nicola Spirig, Ruedi Wild and Melanie Annaheim.

"It's unbelievable feeling to go on the podium in such a hard race with so many good athletes, it's a great success for Swiss Triathlon," he said.

Germany claimed bronze in heartstopping fashion, as Steffen Justus had to serve out a 15-second penalty incurred by Maik Petzold in the second leg.

Just as France's David Hauss appeared around the corner, Justus' time was up and he sprinted out of the penalty box in transition and over the finish line to claim third, denying France a spot on the podium.

Petzold said afterwards he was scared his infringement had cost Germany, the team included Anja Dittmer, Justus and Svenja Bazlen, a medal.

"I didn't know that and we were watching Svenja on the race and I saw just how I jumped on the bike and I was pretty scared and I thought, that's it," he said.

"At the end it was unbelievable that feeling when I saw Steffen staying in the penalty box 15 seconds down and then he just sprinted out and came through, it was amazing."

The ITU Team Triathlon World Championships was launched in 2006 but was re-vamped to the mixed relay team triathlon format in 2009.

In it, competitors race on four-person teams, with two men and two women representing each country, racing in the order of female-male-female-male.

The International Triathlon Union (ITU) is bidding to have the event included on the Olympic programme at Rio 2016.

The format made its major games debut at the inaugural Singapore 2010 Youth Olympic Games, and will also be part of the Incheon 2014 Asian Games.
