Dion Leonard is an ultramarathon runner who has raced across the planet's most inhospitable landscapes, such as the brutal Moroccan Sahara desert and South Africa's Kalahari Desert. One race across the Gobi Desert in China turned out to be a completely different experience when Dion fell in love with a stray dog (later named Gobi) who followed him during the week and completed the race alongside him. Today, Dion and Gobi, along with Dion's wife, Lucja, share Gobi's amazing story in their bestselling books and speaking events.
