In this Young Readers Edition of Impossible First Colin O’Brady recounts his fifty-four-day, unsupported, record-shattering solo crossing of Antarctica using every ounce of his strength, years of training, and sheer force of will.

Prior to December 2018, no individual had ever crossed the unforgiving ice of Antarctica alone, unaided and unsupported. Only one day into what would be a 932-mile journey, O’Brady judged what he was trying to do was impossible.

Alone with his thoughts, O’Brady traveled back in his memory to the events that led him to this pivotal moment. For a while, it had seemed that nothing would stop him: He’d climbed every high mountain peak, bagged every endurance challenge (the Seven Summits, including Everest…record sprints to both Poles…the highest peaks in all fifty US states)—all after recovering from a freak burning accident that doctors said would end his athletic career. But the prize that had eluded him was success on this moment forbidding continent of all.
