Prior to December 2018, no individual had ever crossed the landmass of Antarctica alone, without support, and completely human-powered. But Colin O'Brady was determined to do just that--even though ten years earlier a tragic accident raised doubts that he'd ever walk again normally.

O'Brady's quest drew him into a head-to-head battle with British SAS Captain Louis Rudd--also striving to be "the first." Enduring Antarctica's sub-zero temperatures and pulling a sled that initially weighed 375 pounds in complete isolation and through a succession of whiteouts, storms, and a series of near disasters, O'Brady journeyed 932 miles to a world first. Honest, deeply moving, filled with moments of vulnerability--and set against the backdrop of some of the most extreme environments on earth, from Mount Everest to Antarctica--The Impossible First reveals how anyone can reject limits, overcome immense obstacles, and discover what matters most.
