Epic Scenes From the Pikes Peak Hill Climb, an Auto Race Straight Up a Mountain

The Pikes Peak International Hill Climb has given rabid auto fans and the most daring racers in the country cliff-edge thrills since 1916. This year's 99th edition was no different. More than 40,000 people gathered on the Colorado mountain this past weekend to watch 130 high-powered cars and motorcycles run the 12.42-mile course straight up the side of the mountain. Contestants hit speeds of 150 mph on the way up—with not even a guard rail to shield them along the way.
