This audiobook edition of A Mile at a Time includes additional insights after each chapter from author, Travis Macy, and a bonus track featuring poetry written and read by Travis Macy.

In October 2018, Mark “Mace” Macy, sixty-four years old, was diagnosed with early-onset Alzheimer’s disease. He had spent thirty years competing in Colorado and around the world in ultra-endurance competitions and is one of the few people who have finished all eight Eco-Challenge events. Once diagnosed, he feared losing endurance, strength, and independence.
Mace's son Travis, also a professional endurance athlete, also struggled to see his father battling the disease. In 2019 they decided to participate in World's Toughest Race—a seven-day, grueling 400-mile marathon of trekking, climbing, biking, and paddling through the jungle—for one final race together.

Weaving excerpts from Mace's passionate personal journals alongside a first-person narrative by Travis, A Mile at a Time tells the story of this incredible journey and what both father and son learned along the way.

A powerful story about living—and thriving—with a disease that impacts nearly six million Americans, this timely and deeply moving father-son adventure sheds light on the hard truths of this disease while giving listeners hope of all that still can be achieved.
