Ultramarathons don't leave much room for mistakes. Don't learn the hard way: Get a jump on training for an ultramarathon with Hal Koerner's Field Guide to Ultrarunning, a comprehensive handbook to running 30 to 100 miles and beyond, authored by one of the most experienced and recognized athletes in the sport.   

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. 

Aside from her rock star looks, Catra Corbett is a standout in the running world on her accomplishments alone. And, unbelievably, she's also a former meth addict.

She gives up drugs and moves back home with her mother, abandoning her friends, her boyfriend, and the lifestyle that she came to depend on. Her only clean friend pushes her to train for a 10K with him, and surprisingly, she likes it and decides to run her first marathon after that.

In 1986, the legendary fell runner Joss Naylor completed a continuous circuit of all 214 Wainwright fells in the Lake District, covering a staggering distance of over 300 miles - plus many thousands of metres of ascent - in only seven days and one hour. Those in the know thought that this record would never be beaten. It is the ultimate British ultramarathon. The person taking on this superhuman challenge would have to be willing to push harder and suffer more than ever before. There Is No Map in Hell tells the story of a man willing to do just that.

Marathons have become too easy for some runners. What was once the pinnacle of achievement in a runner's life is now a stepping stone for extraordinary adventure in ultramarathoning. The number of ultrarunners - those running distances of 50k (31 miles), 50 miles, 100k (62 miles), or 100 miles - is growing astronomically each year. To date, there has been no practical guide to ultramarathoning. Now, Bryon Powell has written Relentless Forward Progress, the first how-to manual for aspiring ultrarunners.

Travis Macy has summited glacial peaks in the French Alps, rappelled into limestone caves in China, and raced through parched deserts in Utah.

Macy achieved all of these victories without elite professional training or even exceptional strength, speed, or flexibility.

If running extreme distances is as much about mental endurance as physical, how do you keep going when your internal monologue turns against you?
