1 . The triathlon is a demanding sport. Many say that it is a real test of an athlete’s body and mind. It is difficult because it is three sports in one. It includes swimming for 13. 86 kilometers, bicycling for 180 kilometers, and running for 42. 2 kilometers. The top triathletes finish all three events in about 8 hours.

This sport is a real challenge. First, it takes time to train for competitions. Some people spend up to 8 months training for the race. Second, it takes money to compete. The equipment is not cheap. Bicycles for this event can cost up to$10, 000. Top-quality swimming gear (用具) and running shoes are expensive. Third, athletes must have strong minds. It takes willpower (意志力) to push themselves to keep training to reach their goal.

The triathlon is a recent sport. Triathlons began in California in the early 1970s. In 1978, competitors held the first professional triathlon race in Hawaii. In 1982, this race became famous because of the televised performance of Julie Moss. It was her first competition. Exhausted, she was running toward the finish line. Suddenly, 3 meters before the line, she fell down. She tried to get up, but she kept falling. She finally crawled (爬) across the finish line. She lost that year, but she tried again. Finally, in 1985, she won. This was the start of the triathlon's popularity.

Today, triathlons are much more popular among ordinary athletes. People of all ages can compete, as long as they are in good physical condition. In fact, it has become a great family sport. Triathletes are special people who have time in their lives for careers (事业) and families. Most are highly educated and earn top salaries (薪水) in their jobs. Many triathletes are happily married. In fact, two-thirds of triathletes say that their training has a positive influence on their marriages. Today, the triathlon is an Olympic sport and a respected event worldwide.

2 . There have always been a lot of commonly believed but false ideas about being fat and doing exercise.Some people believe that they can't help putting on weight as they get older,while others hold that if they stop exercising,their muscles will turn into fat.Here are some more myths:

I' ll never lose weight-I come from a fat family

I am fat because I burn calories slowly

Exercise is boring

Wrong!Anything will become boring if you do it repetitively.The key is to develop a balanced and varied program that's fun as well as progressive.If you enjoy a Sunday walk,take a different route.If you do yoga,try a tai chi class.If you like swimming,set yourself a distance or time challenge.

No pain,no gain

Wrong!Exercise is not meant to hurt. Indeed, pain is your body telling you something's wrong, and continuing to exercise could lead to serious injury.You may experience mild discomfort as you begin to exercise regularly,but this is your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly.If they don't,rest and seek medical advice.
