The plan is simple. George and Ben have three weeks to cycle 1000 miles from the bottom of England to the top of Scotland. There's just one small problem - they have no bikes, no clothes, no food, and no money. Setting off in just a pair of Union Jack boxer shorts, they attempt to rely on the generosity of the British public for everything from food to accommodation, clothes to shoes, and bikes to beer.

Deena Kastor was a star youth runner with tremendous promise, yet her career almost ended after college, when her competitive method - run as hard as possible, for fear of losing - fostered a frustration and negativity and brought her to the brink of burnout. On the verge of quitting, she took a chance and moved to the high altitudes of Alamosa, Colorado, where legendary coach Joe Vigil had started the first professional distance-running team. There she encountered the idea that would transform her running career: the notion that changing her thinking - shaping her mind to be more encouraging, kind, and resilient - could make her faster than she’d ever imagined possible.

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?"

Scott Jurek is one of the world's best known and most beloved ultrarunners. Renowned for his remarkable endurance and speed, accomplished on a vegan diet, he's finished first in nearly all of ultrarunning's elite events over the course of his career. But after two decades of racing, training, speaking, and touring, Jurek felt an urgent need to discover something new about himself. He embarked on a wholly unique challenge, one that would force him to grow as a person and as an athlete: breaking the speed record for the Appalachian Trail.

Have you ever wanted to kayak down a gorge in New Zealand? Or run night-time marathons through the Californian desert? How about rollerblading 100 miles around Amsterdam? You have? Then pour yourself a cup of cocoa, get those jim-jams on, and prepare to escape into a world of adventure with this collection of life-affirming short stories from award-winning adventurer Anna McNuff.

At the verge of turning 40, Peter Sagal - brainiac Harvard grad, short, bald Jew with a disposition toward heft, and a sedentary star of public radio - started running seriously. And much to his own surprise, he kept going, faster and further, running 14 marathons and logging tens of thousands of miles on roads, sidewalks, paths, and trails all over the US and the world, including the 2013 Boston Marathon, where he crossed the finish line moments before the bombings.

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.

A man takes on the challenge of a lifetime after hitting rock bottom. He finds himself divorced, unemployed, and in a deep depression when a degenerative eye condition renders him blind with limited light perception. Feeling a calling to run across America, he dedicated the next two years of his life to prepare for, and ultimately run, more than 3,000 miles from California to New York in less than 60 days, averaging 51.5 miles per day, to log the seventh-fastest transcontinental foot crossing in the history of the world.

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.

Anna was never anything like those "real" runners on telly, but when she read about New Zealand’s 3,000-kilometer-long Te Araroa Trail, she began to wonder...perhaps being a "real" runner was overrated. Maybe she could just run it anyway? The Pants of Perspective is a witty, colorful, and at times painfully raw account of a journey to the edge of what a woman believes herself to be capable of. It is a coming-of-age story that will lead you on a roller-coaster ride through fear, vulnerability, courage, and failure.

Why do people race in Ironmans? Only a person whose good sense was severely impaired would decide to do a race marked by such agony and suffering - a race that makes no sense to normal people. Russell Newell would find out when he signed up for the second oldest Ironman in the country: Lake Placid, in the idyllic Upstate New York village nestled in the Adirondacks. Russell would then question his sanity and test his resolve as he attempted to finish the 2018 Ironman Lake Placid...despite almost drowning, crashing on his bike, and more.

In 2008 Sean Conway set off on a 1,000 mile bike ride that would shape the next 10 years of his life, as he became obsessed with the idea of becoming a real ultra cyclist. This is his story, how he tried and failed many times to break a cycling world record, and the story about his final world record attempt, cycling 4,000 miles across Europe. Sean nearly gave up on his dream after tragically losing two of his ultra cycling friends, but decided to continue in their honor with his quest to chase big miles on two wheels.

A London cycle courier with a taste for adventure, Emily Chappell entered an extraordinary new race - The Transcontinental - in which riders must find their own way, entirely unassisted, across Europe in the shortest time possible. On her second attempt, she won the women's event, covering nearly 4,000 miles in 13 days and 10 hours, sleeping in short bursts wherever exhaustion took her.

Matt Fitzgerald has already made a name for himself in the endurance-sport community with books like 80/20 Running, How Bad Do You Want It?, and Iron War. He is an accomplished amateur runner, but if he follows the training, nutrition, and lifestyle of an elite runner, just how fast could he go? He is approaching his mid-40s, so the time to do this is now. He at last has the financial means to do nothing but train.
