A day everyone unites, no border, nationality or language, Ironman World Championship brings us the experience of oneness. This most exciting event is celebrating its 40th anniversary this year. Kona residents have proudly supported the event since 1981. (Started on Oahu in 1978.) We welcome over 2,000 athletes who challenge a 2.4 miles swim, 112 miles bike and 26.2 miles run and more than 5,000 volunteers who support this race. There is another fun event you don’t want to miss in addition to the championship that is called “Underpants Run”. This is held on the Thursday prior to the championship. If you’re curious about what this is, check it out!
