After more than five hours of biking and swimming, triathletes faced a marathon in brutally hot conditions in Kailua-Kona, Hawaii at the Ironman World Championship.

The 42.2K run followed a 3.86K-swim and 180K-bike with the top run times coming in under 2:40 for men and 3:00-flat for women. Canadian Lionel Sanders produced the fourth-fastest marathon among men on the day to finish second overall. There was an 11-minute spread among the top four men’s runners when it comes to their marathon splits while the women’s spread was six minutes, led by Daniella Ryf’s 3:00:02.

Germany’s Patrick Lange produced the fastest run of the day, clocking 2:39:59 for the marathon, off his course record of 2:39:45 from 2016. Temperatures on the Big Island reached 31 C during portions of the marathon on Saturday afternoon.
