The Pikes Peak International Hill Climb — the "Race to the Clouds" — is the second-oldest motor race in America, run since 1916. Cars launch one at a time up the Pikes Peak Highway: 12.42 miles, 156 turns, finishing at the 14,115-foot summit.
It's also one of the most logistically demanding spectator events in Colorado. Watching from the mountain means committing to a pre-dawn entry and a full day at altitude — worth it, but only if you go in knowing that.
