Mark "Mace" Macy (left) was a successful trial lawyer for decades and retired as a partner from his Denver law firm in late 2016. He is also a well-known and long-lived figure in the endurance sports world. Mace and his contemporaries pioneered ultra-running (defined as races of 50 kilometers to more than 100 miles) in the 1980s. In the 90s he did the same for adventure racing: grueling team events requiring everything from rope climbing to trail running, mountain biking, white-water rafting and even camel riding. One of a few athletes to participate in all eight Eco-Challenge adventure races, he is the only person to compete in this extreme adventure race after having been diagnosed with Alzheimer’s. As best as can be ascertained, he is one of the few athletes to officially compete in any sanctioned ultra-distance event after having received such a diagnosis.
