Jonny Brownlee is confident he can edge the sibling rivalry in London on Sunday when he goes head-to-head with brother Alistair for the first time this season.
The younger of the Brownlee brothers, Jonny has found himself playing second fiddle on many occasions during his career, including Alistair coming out on top in both at both the 2012 Olympics and 2014 Commonwealth Games.
His most notable victory over him came in Hamburg two summers ago although the 25-year-old has enjoyed the better start to the 2015 season, winning two out of three World Series races to sit fourth in the overall standings.
Alistair meanwhile has won one and finished second in his two events since returning from injury.
And Jonny, buoyed by his own form, believes he is strongly positioned to record a rare victory over his brother in London.
"I felt like I've been competing as equals with him for the last few years," he said.
"But it's still always been in the back of my mind that if he's in Olympic form, no-one can beat him.
"This year I've been very fortunate with the way my training's gone, with the fact I've raced early and been able to get those races done.
"Being able to get some more training in now means I've got a very good chance of racing him as an equal. Maybe that will change by the end of the season, but in London, definitely."
