Colin O'Brady is a professional endurance athlete who has achieved four world records. He grew up exploring the mountains of the Pacific Northwest and cultivated a passion for adventure in the outdoors. His success swimming in Oregon led him to Yale University. After years as a professional triathlete, he returned to his first love - the mountains. In 2016 Colin conquered the speed records for the Explorers Grand Slam and Seven Summits, a global mountaineering challenge to climb the tallest mountain on every continent including Mt. Everest and ski to the North and South Poles. In 2018 Colin shattered the speed record for the 50 High Points Challenge when he summited the highest point in each of the 50 states in just 21 days. On December 26, 2018 he became the first person to cross the landmass of Antarctica solo, unaided by kites or resupplies. He accomplished the feat in 54 days, covering more than 930 miles along the way, including more than 77 miles in the final 32-hour window where he went without sleep. Throughout the nearly two-month journey, O’Brady never took a full day off.
