Olympic champion Alistair Brownlee won his 15th World Triathlon Series race after victory in Stockholm to go to the head of the world rankings with only the London event remaining.
The 25-year-old was part of a small group that broke away on the bike and Brownlee himself escaped from the leaders in the final stages to build a 20-second lead at the start of the run.
Younger brother Jonathan and Olympic silver medallist Javier Gomez set out in pursuit and they initially made some inroads into Alistair's lead.
However, the elder Brownlee was never in danger of losing his lead and crossed the line first in one hour 43 minutes and 13 seconds ahead of Gomez and Jonathan in third.
He said: "I did all I could to win. I knew my running wasn't quite where I wanted it to be so I had to do a bit of something on the bike."
Victory put him at the top of the rankings for the first time in 2013 with Jonathan Brownlee second and Gomez third.
However, they are so close it means the 2013 ITU World Championship will be decided in the Grand Final race in London between September 11-15.
Alistair added: "It's fantastic to be returning to London. Obviously it's a course that is very fond to me now and to be honest, this year, I never in a million years thought I'd be in a position to win a world title.
"It's been a year of absolute disasters and a bit of a slow one after last year so I couldn't be happier."
