The Ultra Ironman Triathlon Race （超長鐵人三項比賽） is considered one of the most challenging sporting events in the world.Competitors swim，ride a bike，and run.The race is made up of a 3.86-kilometer swim，a 180.25-kilometer bicycle ride，and a 42.2-kilometer run.There are no breaks during the race，so competitors must keep going no matter what.People who choose to enter this race must be healthy and prepared in both mind and body.
   There are several rules for those who want to compete in the Ultra Ironman Triathlon Race.The minimum age of racers is 18，so everyone who competes is an adult.Training for the Ironman can take more than a year.People who train often start practicing the events at shorter distances first and then increase the amount of length and time they swim，bike，and run.Training can be difficult because people need to find a balance of strength and endurance （忍耐力） training.Without enough training，people can get harmed.Some people even put on weight when training because their bodies store calories （卡路里） instead of using them for energy.All people in training should drink plenty of water.
   In the past 40 years，the Ironman has developed from a single race into a global （全球的） movement.Today's Ironman races have events of different distances and racers of different ages.Since 2008，Weihai has held the Ironman Triathlon Race once a year.Weihai Triathlon Sports Association （威海鐵人三項運動協會） was founded in2011.The 2014 World Triathlon Championships （世界鐵人三項錦標賽） was held in Weihai，which was the first time that the event was held in an Asian city.
   Look at the pretty WeiWei，the mascot （吉祥物） of Weihai Ironman Triathlon Race.
   Exercise is good for people's health and helps the heart.People take part in other sports and games such as golf or football，but the Ironman is a challenging way to stay fit.Even though it is hard，it can still be fun.It's a great way to stay active and enjoy life!
