50 Marathons 50 Days: the secrets to super endurance

The ultrarunning legend takes on the ultimate test of endurance: running 50 marathons in 50 days.

Men's Fitness magazine has hailed Dean Karnazes the fittest man on the planet. Time claimed that he is no mere mortal. Wired declared him the perfect human.

Now, Dean proves them right - again - by conquering what no man has undertaken before: 50 marathons in 50 days. That's 2092 kilometers. And five pairs of shoes, 18 pairs of socks, 1,374,721 heartbeats, and three lost toenails.

In 50 Marathons 50 Days , Dean shares his secrets for super endurance. How to adapt quickly to extreme conditions, prevent muscle cramps and overheating, pace yourself when you hit the wall, recover after a gruelling race, and how to stay motivated - against all odds. There's also expert nutrition advice, and a 26-week beginner's marathon training plan.

But the essence of this book goes well beyond the incredible story of those 50 races. Above all, 50 Marathons 50 Days is a fascinating first-hand account of what it's like to push the limits of strength and motivation. It's an inspiring how-to book for anyone looking to go further than ever before towards their goals.
