The Ironman Kona World Championships — a grueling 140.6-mile triathlon in sweltering Hawaii — stream live on NBCSports.com and the NBC Sports app on Saturday.
A year after shattering course records, German Patrick Lange and Swiss Daniela Ryf defend their world titles.
The men’s race starts at 6:25 a.m. local time (12:25 p.m. ET) with the 2.4-mile swim. The women start in Kailua Bay water five minutes later. The swim is followed by a 112-mile bike on the Queen Ka’ahumanu Highway and then a marathon to the Kona finish line.
The fastest triathletes will complete the course in eight hours.
NBCSN coverage runs from noon-2 p.m. ET. NBC and NBCSN will also have occasional check-ins throughout the afternoon, culminating with finish coverage around 8:30 p.m. ET.
On Sunday, NBCSN will air a recap show from 2-3 p.m. ET.
