A large leading group emerged following the swim and it remained that way during the cycling leg.

It was all Murray during the run as he held off the challenge of his compatriots to win his home event at the third time of asking.

"Third time’s a charm they say," he said.

"When I heard about that penalty though, I thought it was a 15 second penalty and I knew the gap to Henri was not that big, so I was pressed.

"That was the hardest I pushed myself in the first race of the season ever."

In the women's race there was a British 1-2 as Lucy Hall clocked 59:34 to pip compatriot Jessica Learmonth who finished in 59:35.

Ai Ueda of Japan came home third in 1:00:04.

"I’m turning 25 next week and I always said that if I can get a World Cup podium before I am 25 then I will be happy."
