"It feels a bit underwhelming because Jonny has collapsed, but, no, it is fantastic," Alistair said. "I am massively proud of Jonny."

"Out of Sladen Beck, I just kept pushing, knowing that Jonny never gives up. I crossed the line exhausted, but very happy to win the race for the third time."

Sat 10 Sep 11: Alistair Brownlee is world champion for a second time.
Alistair has established himself as the favourite for Olympic glory at London 2012 by securing his second International Triathlon Union World Championship, adding to his 2009 title. Joining him on the podium was younger brother Johnny who finished second in the overall standings.
"It's nice to do it twice and show it's not a fluke," said Alistair. "I think this has been my best year, 2009 might look better on paper, but I think this year has been better.
"I've had better races, I've had a few dodgy ones on the way, but I think my best races have been really good and it was great to finish it off here today."
"To be honest I couldn't believe I got away on the bike," Alistair said. "I was worried I would be attacked on the bike."
By finishing first and third respectively, Alistair and brother Jonny have also met GB's selection criteria for the 2012 London Olympics.
The Yorkshireman's challenge looked in threat after his bike suffered a puncture but brother Jonny was able to slow down the pack and allow Alistair back into contention.
"It's one of my proudest races. If you win when things aren't going to plan, you can be really proud of yourself," Alistair said.
Sat 18 Jun 11: Alistair now leads the World Triathlon Championship Series after dominating the Kitzbuhel triathlon.
Despite finishing 44 seconds ahead of his nearest rival, Alistair was wary of over-exerting himself ahead of next week's European Championships in Spain, saying: "I knew I had a decent lead and I knew I was racing next weekend so I didn't push on too much.
"The race would have been easier to control if Johnny was here, that would have made the race a bit different. I've had two great races in two weeks, but I've got to recover and get ready for next week," he added.
Sun 05 Jun 11: Alistair and his brother Jonathan finished first and second at the Madrid triathlon.
It was Alistair's third successive win in the Spanish capital but the first time the brothers have stood together on the podium.
"It had to happen some time and why not have it happen in Madrid, a race where I have done really well," said Alistair, who even had time to wait for and celebrate with Jonathan before crossing the finish line.
Jonathan added: "It's a bit of a strange feeling but really nice that he waited for me - it was really a special moment."
Sun 10 Apr 11: Alistair finished 29th in the opening race of the ITU World Championship Series in Sydney following a fall while leading.
Alistair was out in front and rounding a corner in the rain when he slipped over. He never got back into the race and Javier Gomez crossed the line first.
His brother Jonathan, who took second place, said of Alistair's fall: "I shouted 'just get up, get up'. At first it was a bit of a shock because he was looking really good coming down the hill. That's the sport, he fell over. It's a shame really."
British Triathlon coach Mark Pearce said: "He took a knock when he fell, but it's nothing serious."
The Serpentine lake will host the 1.5km swim whilst the 10km run and 40km cycle will take in Buckingham Palace. This year's Hyde Park triathlon will act as a test event for the Olympics and has been scheduled for 6-7 August.
