Charlie Engle, author of the memoir Running Man, is something of an expert on endurance. Running helped him overcome a crack cocaine and alcohol addiction and keep his spirits up while in prison, where he inspired other inmates by running in endless circles around the track. For Engle, the more extreme the run, the better — think the Sahara Desert. “For years, I listened to music when I ran,” he says. “I would speed up and slow down with the beat of the songs.” Then, he says, he found audiobooks. “Once I discovered that I could be transported to other locations — or into the middle of family dramas or dead center into a hurricane — simply by listening to someone telling me a story, I never looked back.”

People have been extolling the virtues of audiobooks for helping them stay motivated during long runs — they’re also great for incentive. “I find that I really look forward to my next run when I am in the middle of a great book,” says Engle. “The running will always be tough but the miles float by much easier when I am immersed in a great novel.”

Here are some of the books Engle recommends for staying motivated and distracted.

(Bonus points: These are more or less in order of how intense the run was as he listened.)
