In 2016, Dion Leonard, a seasoned ultramarathon runner, unexpectedly stumbled across a little stray dog while competing in a gruelling 155 mile race across the Gobi Desert. The lovable pup, who earned the name ‘Gobi’, proved that what she lacked in size, she more than made up for in heart, as she went step for step with Dion over the treacherous Tian Shan Mountains, managing to keep pace with him for nearly 80 miles. As Dion witnessed the incredible determination of this small animal, he felt something change within himself. In the past he had always focused on winning and being the best, but his goal now was simply to make sure that his new friend was safe, nourished and hydrated. Although Dion did not finish first, he felt he had won something far greater and promised to bring Gobi back to the UK for good to become a new addition to his family. This was the start of a journey neither of them would ever forget with a roller coaster ride of drama, grief, heartbreak, joy and love that changed their lives forever
