Have you ever taken part in a marathon? A marathon is 42km long. It is the longest race in the world. To make the runner’s body work, harder training(训练) is quite necessary. A runner should start to prepare for a marathon at least three months before. Many hours of running at different speeds(速度) and the changes in diet are necessary in the training.

Two weeks before the marathon, the training programme becomes less, from 100km per week down to 60km and then to 30km in the final week. On the last two days they may not run at all.

Breakfast should be eaten at least three hours before the race. Easily digested (消化) food such as cereal (麦), toast (烤面包) and scrambled (捣碎) egg is best, with as much fluid (液体) as possible. Runners should drink water about half an hour before the race to keep up the body fluid.
