Dion Leonard is an ultra-marathon runner who lives for the toughest races in the world. When he travels to China for the 7-day race through the Gobi Desert, his primary goal is to win the competition. He packs light and brings only the essentials for food. What he doesn't expect is the little mixed-breed dog that looks at him with her big brown eyes at the starting line—and then accompanies him for miles. He names her Gobi, and she gives him courage when he thinks about giving up. Ultimately, he turns back for her during the race. In this book, Leonard shares how the little dog with a big heart made him a better person. Leonard and Gobi's story illustrates the strong bond that can exist between a man and his dog, and what people can achieve when they work together.
