Until five years ago, Alexandra Heminsley was decidedly not a runner. Nor was she athletic in any sense of the word. She was an ordinary, curvy woman who was convinced that sports of any kind, especially running, were beyond her. But she's made running part of her life, and gets to reap the rewards: not just the obvious things, like a touch of weight loss, health and glowing skin, but self-belief, and immeasurable daily pleasure.

Humans, unlike other animals that are drawn to water, are not natural-born swimmers. We must be taught. Our evolutionary ancestors learned for survival; now in the 21st century, we swim in freezing Arctic waters and piranha-infested rivers to test our limits. Swimming is an introspective and silent sport in a chaotic and noisy age; it’s therapeutic for both the mind and body; and it's an adventurous way to get from point A to point B. It's also one route to that elusive, ecstatic state of flow.

On September 2, 2013, at the age of 64, Diana Nyad emerged onto the sands of Key West after swimming 111 miles, nation to nation, Cuba to Florida, in an epic feat of both endurance and human will, in 53 hours. Diana carried three poignant messages on her way across this stretch of shark-infested waters, and she spoke them to the crowd in her moment of final triumph.

For David Goggins, childhood was a nightmare--poverty, prejudice, and physical abuse colored his days and haunted his nights. But through self-discipline, mental toughness, and hard work, Goggins transformed himself from a depressed, overweight young man with no future into a US Armed Forces icon and one of the world's top endurance athletes. The only man in history to complete elite training as a Navy SEAL, Army Ranger, and Air Force tactical air controller, he went on to set records in numerous endurance events.

Our ancestors crossed deserts, mountains, and oceans without even a whisper of what anyone today might consider modern technology. Those feats of endurance now seem impossible in an age where we take comfort for granted. But what if we could regain some of our lost evolutionary strength by simulating the environmental conditions of our forbears? Investigative journalist and anthropologist Scott Carney takes up the challenge to find out: Can we hack our bodies and use the environment to stimulate our inner biology?

As a journalist whose career spans three decades, CNN correspondent Tom Foreman has reported from the heart of war zones, riots, and natural disasters. He has interviewed serial killers and been in the line of fire. But the most terrifying moment of his life didn't occur on the job - it occurred at home, when his 18-year-old daughter asked, "How would you feel about running a marathon with me?"

After 30 years of a healthy, rewarding, and exciting life, I wake up in a hospital bed unable to move. The neurosurgeon leans down and breaks the news: You won't regain any function in your body and you will never walk again. My medical insurance sends me home, discontinues my care, and tells me to "adapt to my new life". Little Big Steps is the story of the pivotal moments, interactions, and breakthroughs following the injury that turned my life upside down.

From the best-selling author of Kafka on the Shore comes this rich and revelatory memoir about writing and running and the integral impact both have made on his life. Equal parts training log, travelogue, and reminiscence, this revealing memoir covers Murakami's four-month preparation for the 2005 New York City Marathon. Settings range from Tokyo, where he once shared the course with an Olympian, to the Charles River in Boston, among young women who outpace him.

On the way home from swim practice, 18-year-old athlete Brian Boyle’s future changed in an instant when a dump truck plowed into his Camaro. He was airlifted to a shock-trauma hospital. He had lost sixty percent of his blood, his heart had moved across his chest, and his organs and pelvis were pulverized. He was placed in a medically-induced coma.

An inspirational memoir by a man who became an elite wheelchair athlete after suffering a catastrophic spinal injury and who finally walked again 25 years after his accident. After two years of intense physical therapy following his crippling accident, John Maclean set a new course for himself when his father encouraged him to embrace his new reality and asked: "How far can you go"? Inspired, Maclean became the first paraplegic to complete the Ironman World Championship and swim the English Channel before going on to win a silver medal for rowing at the 2008 Paralympic Games.

In 1975, 23-year-old Englishman Tom Michell follows his wanderlust to Argentina, where he becomes assistant master at a prestigious boarding school. But Michell's adventures really begin when, on a weekend in Uruguay, he rescues a penguin covered in oil from an ocean spill, cleans the bird up, and attempts to return him to the sea.

One Breath is a gripping and powerful exploration of the strange and fascinating sport of freediving, and of the tragic, untimely death of America's greatest freediver Competitive freediving - a sport built on diving as deep as possible on a single breath - tests the limits of human ability in the most hostile environment on earth.

Mourning the death of his father and gravely injured at the hands of the English, Jamie Fraser finds himself running with a band of mercenaries in the French countryside, where he reconnects with his old friend, Ian Murray. Both are nursing wounds, both have good reason to stay out of Scotland, and both are still virgins despite several opportunities to remedy that deplorable situation with ladies of easy virtue.

This is not your standard how-to manual. It is very different. The purpose of Scuba Fundamental is not to teach you how to dive. A dive instructor will do that. But this book will make the learning process much easier. It will help you make the right choices and avoid the pitfalls that await new and uninformed divers coming into the sport. It will also set you well on the road to becoming a capable and competent lifelong diver.
