A marathon is a long running race of 26.2 miles (42.195 kilometres). The first Olympic Marathon was held in Athens. Now, many cities host their own marathons every year. Some of the best- known marathons around the world are the New York City Marathon, the Boston Marathon and the Tokyo Marathon. Among them, the Boston Marathon which started in 1897, is the oldest yearly marathon in the world. As time goes by, the sport has become more than just a race.
Themes of marathons add fun and meaning to the hard miles. Runners run for helping sick kids, celebrating important events, or just enjoying nature. There is a famous marathon in Gisborne, New Zealand, which is known for being the first city in the world to welcome the sunlight every day. Runners can greet the sunrise as they race along the golden sandy beaches.
Marathon routes bring people more understanding of the old sport. Some routes provide great sporting challenges for runners. The routes offer various surfaces, from bridges to sand to hills. Runners of all skill levels can sweat freely and push their limits in the race. Some routes are well planned for runners to explore the many sides of a city. For example, the route of the Great Wall Marathon takes the runners along the great wonder of the world. The race can be an amazing chance to get to know Beijing, its people and local food.
A marathon is quite a journey for runners to enjoy the run, challenge themselves and experience the culture. There is so much more behind the race for us to explore.
