Hill Climb

摘要

Pikes Peak, the second highest mountain in Colorado, reaches 14,109 feet above sea level. In 1916, race cars began to compete over a road built to the top of the mountain. Each car ran against the clock, and the one that took the least time to reach the top was the winner. The Pikes Peak International Hill Climb is still run every year on the Fourth of July, its basic format unchanged, and the climb is still a severe test for man and machine: The lack of oxygen induces altitude sickness in humans, and engines begin to wheeze as they lose power at high altitude.
