In this episode of The Exercise Mechanic Podcast, Etienne and Ryan sit down with ultra-endurance athlete and Guinness World Record holder Morgan McKay. From competing in World’s Toughest Mudder to conquering the Spartan Ultra in Iceland and setting a record for the fastest 10K carrying 100 lbs, Morgan’s story is one of resilience, mindset, and sheer mental toughness.
You’ll hear how Morgan went from a self-described “terrible cross-country runner” to one of the top names in obstacle course racing. She opens up about balancing motherhood, marriage, and training, and why community, teamwork, and planning have been keys to her success.
Whether you’re an endurance athlete, a fitness coach, or just someone fascinated by what it takes to push through the “pain cave,” this conversation will leave you inspired.
