Double Olympic champion Alistair Brownlee announced over social media today that he will be undergoing surgery tomorrow for his chronic hip problem and thus will be out of competition for the remainder of the year. The British athlete was pegged as a favourite heading into next month’s Ironman 70.3 World Championship where he was set to race for the first time, building on his win at the Ironman 70.3 North American Championship in May.

“Unfortunately it will take me away from competing for the rest of the year but I hope it will enable me to continue doing what I love for many years to come,”he says.

Besides the 70.3 worlds, Brownlee will also have to withdraw from competition from the rest of the year in the Super League Triathlon including its September race near his hometown in Jersey, UK.
