On June 3rd 2017, professional climber Mark Synnott was in Yosemite to witness something that only a handful of people knew was about to occur: his friend, Alex Honnold, was going to attempt to summit one of the world's most challenging ascents, a route called Freerider on the notorious rock formation El Capitan. It is an extraordinarily dangerous and difficult climb, and yet Alex was going to do it 'free solo'. Meaning no help. No partner. No equipment. No rope. Where a single small mistake would mean certain death. Indeed, to summit El Cap free solo was a feat likened to Neil Armstrong first walking on the moon.

As Alex plots, rehearses and ultimately attempts his heart-stopping ascent, Mark also shares his own personal history of climbing, filled with triumphs, defeats and dilemmas, in this deeply reported, inspiring exhortation to live life to the fullest.

"An enthralling new book. Few sports have as rich and varied a literature as climbing...and this gripping work from the vastly experienced mountaineer and adventurer Mark Synnott is a magnificent addition to the canon...This compelling book reads like a thriller as it ranges over the rarefied world of extreme climbing." - Daily Mail

"An accomplished portrait of two remarkable lives" - New York Times Book Review

"Fast paced and enjoyable." - Wall Street Journal

"Synnott, with the skill of a master craftsman, weaves into this text stories about Alex's climbing. . . . fascinating reading. . . . Synnott uses his experience both as a climber and as a writer to paint an incredible canvas. The Impossible Climb is not to be missed." - Climber
