CNN
After completing 50 triathlons in 50 days across all 50 US states, James Lawrence knew he could do more.
"The 50 wasn't close enough to know my limits," Lawrence tells CNN Sport. "That is why I am doing the 'Conquer 100.'" A full-distance or Ironman triathlon involves swimming 2.4 miles (3.8 km), cycling 112 miles (180km), and running 26.2 miles (42.195km).More Related News
