Colin O’Brady is a multiple world record holder and is considered one of the world’s premier endurance athletes. Among his feats are a first-ever solo, unsupported and unaided crossing of Antarctica; the speed record for the Explorers Grand Slam—summiting the tallest peak on each continent and journeying to both Poles; and topping the highest point in all fifty US states in just twenty-one days. A Pacific Northwest native, he now lives in Portland, Oregon, and Jackson, Wyoming, with his wife, Jenna Besaw. He is the author of The Impossible First.
