Retirement is proving to be a busy time for Apolo Ohno.
First, the former Olympic speedskater returned for a second stint on "Dancing With the Stars.”
Now, he is taking on the Ironman World Championship.
Ohno has announced he plans to enter the Hawaiian triathlon in October. He will have to swim 2.4 miles, bike 112 miles and run a marathon.
Those are long distances for an athlete who won eight Olympic medals in short track events that lasted only a few minutes each.
“No turning back now,” he wrote on Instagram.
Ohno is following in the footsteps of former NFL receiver Hines Ward, another “DWTS” alumnus who competed in his first Ironman last fall, finishing the grueling race in just over 13 hours.
