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 is quite necessary. A runner should start to prepare for a marathon at least three months before. Preparation includes races many hours of running at different speeds, and changes in diet. During the training period, the runner must eat a regular and balanced diet. The diet should include a lot of carbohydrates to supply the energy needed in training.
In the early days of training, runners cover 80km per week. The weekly total is increased every two or three weeks and at least two long runs per week are added.
Two weeks before the marathon, the training program is reduced, from 100km per week down to 60 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 food such as cereal, toast and scrambled egg is best, with as much fluid as possible. Runners should drink water about half an hour before the race to keep up the body fluid levels.
