Excitement Builds for the Ironman Triathlon World Championship in Kona, Hawai

The Ironman World Championship will stream live from Kailua-Kona, Hawaii on Saturday, October 14th as the top pros and age groupers compete. Athletes will endure a 2.4 mile swim, a 112 mile bike ride, and a 26.2 mile run along the black lava fields of the Kona Coast.

The pro’s are inspiring to watch as they go for the World Championship title, but the age-groupers are just as inspiring as many of them struggle just to finish before the cutoff time of 17 hours!
