Hawaii is the birth place of the IronMan triathlon where in 1978 Judy and John Collins challenged individuals to swim bike and run 140.6 miles and joked they would call the winner an “Iron man”. The event now sees 1000s of athletes test themselves in IronMan races all over the globe, including myself. But Kona, home to the Ironman World Championships which begins today (6th October 2022), holds something special for all triathletes. The history of the race is full of epic tails of survival (see the story of Julie Moss or Sian Welsh & Wendy Ingraham) and infamous battles such as the Iron War (between Dave Scott and Mark Allen). The weather is generally consistent and therefore predictable in Kona in October: sunny, windy and humid. However, while the air temperatures are generally around 30 oC which are not necessarily remarkable, it is the humidity “swamp-like” conditions that really challenge athlete’s thermoregulatory capacity when competing in the Ironman World Championships.
