Running a marathon (马拉松)
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 may have races, many hours of running at different speeds and changes in diet(饮食). During the training time the runner must eat a fit diet.  The diet should have lots of things needed in training the players.
In the early days of training, runners run 80km per week. The running is increased every two or three weeks and at least two long runs per week are needed.
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.

What are the limits(极限) of human body? The BBC’s Focus magazine has some answers.

How cold can you stand?

Normal body temperature is around 37℃. At 35℃ you’re unable to write your name. Even walking is very difficult. At 33℃ you may find it difficult to think, understand and form(形成) opinions properly. By the time you have cooled to 20℃, your heart would have stopped beating.

Limit: 0℃. Ice would form in your tissues(纤维组织), killing all the cells.

How spicy can you eat?

There is capsaicin(辣椒素) in many foods. The more capsaicin, the hotter the dishes are. If you’re healthy enough, you can survive(存活) eating a teaspoon of pure capsaicin. But you would find it impossible to eat anything else for a few hours.

Limit: 5g capsaicin.

How fast can you run?

The fastest man in the world is Asafa Powell. The runner finished the 100m in 9. 74 seconds in 2007. This gives an average(平均的) speed of 36. 96km/h.

Top runners are at their fastest around 80 metres, so a runner’s greatest speed may reach 43.06km/h.

Limit: 43.06km/h.

How loud is too loud?

The loudest sound you can hear is 168 dB(分贝). Sound louder than that may do harm to your ears. The loudest sound ever recorded was the eruption of Krakatoa(卡拉卡托火山爆发) in 1883. It was 180 dB, 160km away.

Limit: 168 dB
