Iron Man World Championship

The greatest sporting weekend of the year has arrived! The Ironman World Championship takes place tomorrow, Saturday, October 14. Thousands of the best triathletes from around the globe have ventured to Kailua-Kona, Hawai’i to battle each other, the grueling hot, humid, and windy island conditions, and themselves through the 2.4 mile swim, 112 mile bike, and marathon (26.22 mile) run.

Hoping to build off of the success of FuelBelt athlete and triathlon legend Crowie Alexander, three-time Ironman World Champion and course record holder, FuelBelt athlete Josh Amberger, will make his debut performance on the Big Island. While Josh has never raced through the lava fields of the Big Island, he toes the line with the 2017 Ironman Asia-Pacific Championship win (and course record) under his belt. After dominating Ironman Maastricht this year, Kona veteran, XTERRA World Champion (2011) and Fuelbelt athlete Michael Weiss will also present a force to be reckoned with.

Cheer them and the other 2,400 + dedicated, determined athletes on, no matter where you are. Here’s how to watch the race in the U.S.:
