To make the race "less boring" last weekend at the Zurich Ironman, French triathlete Victor Mellerin set his own handicaps to complete the 3.8km swim, 180km cycle and 42.195km run.
The 26-year-old chose to swim butterfly, which is the most demanding stroke, to ride an ancient bike and run the marathon wearing crocs, which are the least stabilising for the foot.
"I didn't injure my feet, even no blisters! I'm the first surprised because I didn't test the crocs before. I just trained by running in the snow last winter during 5-hour sessions" Mellerin said to L'Equipe.
Before running the swimming teacher had to deal with a 25kg bike dating back to 1946.
"It comes from the Swiss army. By the way it's more a tank than a bike!"
