The Marathon

The marathon is the longest race at the Olympics. You have to be a very strong runner to win the marathon.

The marathon is 42.195 km long. Why is it 42.195 km and not 43? The 1908 Olympics was in London. The King of England wanted his children to watch the marathon so the race started at the gate of his palace. From there to the finish line was 42.195 km.

One of the best marathon runners was Abebe Bikila. He was from Ethiopia. He won the gold medal in the marathon at the 1960 Olympics. He ran the whole race without shoes on!
