Olympic champion Alistair Brownlee delighted the home British crowd by leading home his brother Jonathan in a 1-2 at the World Triathlon Series event in Leeds today.

The popular result was what fans lining the streets of the city wanted to see with both siblings coming from Leeds, which was hosting an event at this level for the first time.

Both Brownlees emerged from the 1500 metre swim among the leaders and the duo built a large gap in the cycling leg alongside Australia's Aaron Royle and Aurelien Raphael of France.

During the run, the brothers needed only seconds to move into the gold and silver spots and while the two ran together for a couple of minutes, Alistair clicked into gear to move ahead of his younger brother.

He eventually came home in 1hr 49min 27sec with enough of a gap to walk into the finisher’s chute.

Jonathan, the London 2012 Olympic bronze medallist, finished in 1:49:59 as Royle came home in 1:50:33 for bronze.

Spain's Mario Mola, the overall Series leader, opted not to race in Leeds.

"I think I have said that the Olympics was the best race I have ever raced in, but now I think that just beat it," said Alistair Brownlee.

"The run was absolutely phenomenal, by far the best World Series there has ever been.”

In the women's race, the United States' world champion Gwen Jorgensen came out on top.

The American overcame a deficit at the start of the run to make it back to back World Triathlon Series titles after her victory in Yokohama in May.

Britain's Jess Learmonth and Lucy Hall emerged first after the swim and left the first transition with Bermuda's Flora Duffy.

All three maintained their lead for the entirety of the 40 kilometre bike section, with Jorgensen nearly 90 seconds behind the trio going into the 10km run.

The eventual winner had passed Hall before the final 2.5km lap and she then caught Learmonth and Duffy before striding away to the line in a winning time of 2:00:33.

Duffy, the overall leader, took silver in 02:01:24 with Vicky Holland, who was in the second pack during the cycling, advancing during the run for a British bronze in 2:01:57.

Learmonth eventually had to settle for 10th with Hall 13th.

"It’s the first time here, so I didn’t know what to expect but the crowds were just amazing and they really welcomed us to the city," said Jorgensen.
