#752 - Mike McCalley: How a Brutal Wake-Up Call From His Son Changed Everything

Mike McCalley shares the unlikely progression from being unable to jog a quarter mile to training for and racing some of the biggest endurance events in ultrarunning.

This conversation centers on a turning point with his son, the habit changes that followed, and how he built the fitness, durability, and mindset to pursue Leadville, Wasatch, and the broader Grand Slam goal.

In this episode, Mike McCalley discusses the family moment that sparked his return to fitness, the practical systems he used to lose weight and build consistency, and how he shifted from general health work to a true athlete’s mindset. We also talk through the role of coaching, elevation, blood work, trail running, and why the process matters as much as the outcome.
