On August 21, 1968, the 19th Summer Olympics were held in Mexico City, Mexico. The choice of Mexico City as the host city for the Games was controversial due to the city’s high altitude and low oxygen levels. The altitude of Mexico City reached an average of 2,300 meters, and the air oxygen level was 30% less than that of other cities.
However, it was precisely these conditions that made Mexico City’s Olympics unforgettable. The American track and field athlete Ken Holman became the first American to win a gold medal at the Mexico City Olympics by finishing the men’s marathon.
The Mexico City Olympics also had a lasting impact on the world. It began to draw attention to the effects of altitude and low oxygen levels on athletes and gradually led to a growing awareness of the importance of environmental protection. This made the Mexico City Olympics a significant part of the Olympic history and a turning point for human sports and environmental awareness.
