Ironman is a legendary race that has been held in Hawaii since 1978. It was founded by the officers of the US Navy who liked the idea to challenge their physical endurance. Since then every year, a few thousands of enthusiasts and professional athletes test their will and bodies in a Triathalon Championship that includes swimming about 4 km, a bike race of 180 km, and a marathon of 42 km. It takes around 8 hours to complete such an extreme exercise for top athletes, but everyone who crosses the finish line truly deserves the Ironman title. Every year thousands of athletes participate in this race and because of its popularity, you have to enter a lottery to get in. So if you think you are tough enough to be called an Ironman, sign up now!
