hero - he has won the running competition! You may live very far from Greece and maybe you haven't heard about the Olympic Games, so I'll explain you what they are.The first Olympics were held 12 years ago. ft was a part of a great religious festival that was held fo honour of the Olympic Gods. Since then we have had the Olympic Games every four years. The best athletes compete in running. We call it sprint. The athletes should run the distance of the hundred and eight meters. I'm so proud because today it was my son who did it the fastestThe Games are so important that even wars are stopped when they are held. They contain only one sports event - sprint competition, but j sure that very soon the programme will include a lot of other sports like jumping, wrestling, racing and riding.
