    Kenya’s long-distance runners are among the best in the world. Is their food and daily routine (常规) a key to the secret of their success? We spent a week at a training camp with ten top athletes (运动员) to find out. This is what we discovered.

They eat five times a day:

08:00      Breakfast

10:00      Mid-morning snack

13:00      Lunch

16:00      Afternoon snack

19:00      Supper

The Kenyan runners’ food is based on bread, rice, potatoes, porridge, cabbage, beans and ugali (balls of cornmeal). Ugali is usually eaten with vegetables.

Meat is eaten in fairly small amounts, just four times a week. The athletes drink a lot of tea with milk and sugar. They get all the vitamins (维生素) they need from their food — they never take vitamin pills.

They usually train as a group twice a day. The first run is at 6 o’clock in the morning and the afternoon run is at 5 o’clock. They run 10 to 15 kilometres in the morning and 6 to 8 kilometres in the afternoon. Once a week, the two 1,500-metre runners in the group run shorter distances at higher speeds.

An amazing part of the Kenyan food is its richness in carbohydrates (碳水化合物). Every 24 hours, they have about 600 grams of carbohydrates to give them energy for their training. They only eat a little fat, most of it coming from the milk they have in their tea. They drink about a litre (升) of water every day. Surprisingly, they drink more than a litre of tea every day, too. They always eat soon after training.

Rest and sleep are also an important part of the athletes’ programme. They are always in bed early and they always get a good night’s sleep.
