After years of watching Kenyan athletes win the world's biggest races, Adharanand Finn set out to discover just what it was that made them so fast - and to see if he could keep up. Packing up his life he moved from Devon to Iten, in Kenya, to eat with, interview, sleep beside and - most importantly – run with, some of the greatest runners in the world. In the distance rests his dream, to join the best of the Kenyan athletes in an epic first marathon across the Kenyan plains.

New York Times best-selling author and ultramarathoning legend Dean Karnazes has pushed his body and mind to inconceivable limits, from running in the shoe-melting heat of Death Valley to the lung-freezing cold of the South Pole. He’s raced and competed across the globe and once ran 50 marathons, in 50 states, in 50 consecutive days.

In 2017, journalist Matt Hart received a USB drive containing a single file. He quickly realized he was in possession of a stolen report prepared a year earlier by the United States Anti-Doping Agency (USADA) as part of an investigation into legendary running coach Alberto Salazar, an endocrinologist named Dr. Jeffrey Brown, and cheating by Nike-sponsored runners, including some of the world’s best athletes. Combining sports drama and business exposé, Win at All Costs tells the full story of Nike’s running program, uncovering a corporate win-at-all-costs culture.

In 2017, world-class ultrarunner Hillary Allen was at the top of her sport - and it felt like she was running on top of the world as she competed in Norway's Tromsø Skyrace. Allen was nearly halfway through the 50-kilometer race when she fell 150 feet off an exposed ridge, fracturing her back and breaking multiple ribs, both feet, and both of her lower arms. Beginning with the dramatic story of her accident and rescue, Out and Back: A Runner's Story of Survival Against All Odds recounts Allen's fight to return to the life she loves.

Ultra running defies conventional logic. Yet this most brutal and challenging sport is now one of the fastest growing in the world. But is it an antidote to modern life or a symptom of a modern illness? Adharanand Finn travelled to the heart of the sport to find out - and to see if could become an ultra runner himself. His journey took him from the deserts of Oman to the snow-capped peaks of the Rockies, and from a 24-hour track race in Tooting to his ultimate goal, the 105-mile Ultra-Trail du Mont-Blanc.
