BORDER iron man Chris McDonald won more than prizemoney this week when he went back-to-back in the Louisville ultra-marathon.
It was also the now US-based athlete’s fourth win.
McDonald had suffered through 40-degree temperatures and 70 per cent humidity for almost nine hours before collapsing after crossing the line.
The father of three-week-old twins, hit the front in the marathon run leg at 9½-kilometre mark and had just 16 seconds to spare at the finish.
As a result of his incredible record, McDonald was also given the key to the city by the mayor Greg Fischer.
McDonald told local media he would return to defend the title next year.
“I would love to still be a part of the race as an athlete ambassador or something, because it means so much to me,” he said.
