"This is going to be a true test, there is no easy part to this race at all," Jonny said. I can't wait. The race starts with a 750m swim in Schwarzsee lake followed by an 11.55km cycle ride that features gradients reaching 22% and a 2.55km run over uphill trails. The Brownlee brothers are unbeaten this year, with Alistair winning the San Diego triathlon - the only one he has competed in. "It's great to be here, I'm really excited about this one as it's something new and very different from what we've done before," said the 25-year-old. Britain's Jodie Stimpson starts the women's race third in the rankings behind Gwen Jorgensen, of the United States, and Germany's Anne Haug. It's pretty amazing being ranked third in the world. I couldn't have dreamed it to be honest and it seems very unreal," said the 24-year-old. The race in Kitzbuehel is exciting and totally unknown to everyone.
