At his heaviest, Mac weighed 530lbs.
Through relentless effort, and sharing his fears, struggles and triumphs with others, he lost an amazing 300lbs and inspired thousands of people across the country with his extraordinary adventures.
Sadly, he would regain 250lbs in the ensuing years.
Now Mac joins up with Tim Scrivner, founder of Jailbreak Race Events, for the Relentless Road Podcast, a social experiment in the power of positive peer pressure, and possible public humiliation, as he endeavors to lose the weight, reclaim his health and inspire others as he embarks on new adventures.
