Apolo Ohno is taking on a new challenge in retirement, one of the greatest challenges in sports.
The most decorated U.S. Winter Olympian ever is training to compete in the World Ironman Championships in Kailua-Kona, Hawaii, in October.
Ohno will attempt to swim 2.4 miles, bike 112 miles and run a marathon back to back to back. Ohno, 31, won eight Olympic medals from 2002 to 2010 never skating at an individual distance greater than 1500m.
The world’s best athletes take more than eight hours to complete an Ironman. Ohno’s longest short track races took a few minutes.
“I’m still not entirely sure I can grasp the difficulty of this,” Ohno told The Associated Press.
Retired Pittsburgh Steelers wide receiver Hines Ward and celebrity chef Gordon Ramsay entered last year’s World Ironman Championships.
