As announced on the Commerzbank Triathlon Team website today, Germany’s Normann Stadler has retired from professional triathlon racing.

After undergoing heart surgery at Heidelberg University Hospital on July 4th to repair a failing heart valve and a nearby aortic aneurysm, the 38-year-old two time Ironman World Champion (2004 and 2006) simply stated the following.

“I am flattered that so many people believe in my comeback. Nevertheless I know that I wouldn’t be able to achieve a world class level again,” said Stadler.
