Sports Illustrated captured the 40th Ironman World Championship in Kailua-Kona, Hawaii, on Oct. 13, which saw the defending champions win again. Daniela Ryf, 31, of Rumisberg, Switzerland, lowered her course record to 8:26:18. Patrick Lange, 32, of Bad Wildungen, Germany, won the men's race in 7:52:39, becoming the first person ever to finish in under eight hours.
Look back at all the action from the 2016 Ironman World Championship in Kona, where Germany's Jan Frodeno took home his second-straight title for the men's division and Daniela Ryf defended her title—and broke a record—in the women's division.
Germany's Patrick Lange, Sebastian Kienle, Switzerland’s Daniela Ryf, Australia’s Mirinda Carfrae and American Heather Jackson are among the top contenders for the 2018 Ironman World Championships in Kona.
