A Mile at a Time

An inspiring memoir about a father and son entering World's Toughest Eco-Challenge Fiji despite one of them battling Alzheimer’s.

“Travis and Mace have touched a generation of families around the world with their courage, resilience and kindness.”

-- Bear Grylls, star of Man vs. Wild and host of World’s Toughest Eco-Challenge Fiji

“Watching Mark and Travis Macy compete together for Eco-Challenge Fiji was a true inspiration. Travis’s selfless act of taking his father on what may be his last race is a story that anyone can relate to and what we need more of these days.”

--Mark Burnett, chairman of MGM Worldwide Television Group; creator and producer of Survivor, The Apprentice, and World’s Toughest Eco-Challenge Fiji

In October 2018, Mark “Mace” Macy, sixty-four years old, was diagnosed with early-onset Alzheimer’s disease. Mace 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, Mace 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 readers hope of all that still can be achieved.
