This year, Europe represents 46% of the field, while North America closely follows with 34% of athletes registered to race in the IRONMAN World Championship. Asia-Pacific brings 8%t of participants, with South America at 7%.

“The evolution of this race over the past 40 years, from its modest beginnings to the iconic globally recognized phenomenon it has become, is truly extraordinary,” said Andrew Messick, president and CEO of IRONMAN. “From the very first race on the shores of O‘ahu, Hawai`i in 1978, IRONMAN has carved out a unique legacy in sports history and the pinnacle IRONMAN World Championship event showcases the best global competitors from around the world every year. We look forward to the next 40 years as our athletes continue to shape history through extraordinary feats and life-altering journeys.”

The 2018 field of athletes will tackle the ROKA 2.4-mile ocean swim in Kailua Bay, followed by the Ventum 112-mile bicycle ride along the Queen Ka‘ahumanu Highway from Kailua-Kona to the turnaround in Hawi, capped with a 26.2-mile HOKA ONE ONE run beginning on Ali‘i Drive, where spectators pack the roads, up Palani Road to the Queen Ka‘ahumanu Highway, before making their way to the infamous Natural Energy Laboratory of Hawai‘i Authority.


Athletes will complete their journey to the roar of tens of thousands of spectators as they cross the historic Ali’i Drive finish line.

The United States of America is the most represented nation with 640 registered competitors, followed by Germany (215), Australia (208), and the United Kingdom (130). Athletes will travel from 46 U.S. states, with the greatest number coming from California (91), followed by Hawai‘i (45), Texas (44), Colorado (38) and New York (35).
