Red Bull Aces is the world’s first-ever wingsuit slalom competition, with athletes racing four at a time through a one mile-long course made of five 112-foot long gates suspended thousands of feet in the air. Athletes jump in heats of four from a civilian Bell Huey helicopter at an altitude of 8,000 feet above sea level, and must weave between five gates positioned at descending levels between 6,500 feet and 3,500 feet. The winner is based not only on how quickly the finish line is crossed, but also on how many gates he/she correctly passes through. The event was first held in 2014, and returned this year to bring the best wingsuit athletes in the world to compete in Cloverdale, Ca. Andy Farrington of the United States fought off a fierce challenge from an international field of 40 men and women from 18 countries to claim his second consecutive Red Bull Aces championship.
