EB63: From Inactivity to Endurance Sports Vacations, 100 Mile Lessons, Metabolic Efficiency, and Huge Benefits of Simple Core Routine – Hog’s Hunt 50k – Our Chat with Jeff Irvin


Drinking a beer and eating pizza on the couch.

A P90X infomercial comes on the screen.

Jeff Irvin of Texas was in his early 30s, inactive, and the numbers on the scale getting bigger with each passing year.

Jeff decided at that moment, he needed to change. 90 days of P90X began the journey.

“It kicked my ass.”

The journey continued including running and triathlon where endurance sports had become a lifestyle for both him and his wife. Along the way, Jeff began to place his tread more frequently on the trails with its laid back vibe and the memories it brought back of his youth in western Pennsylvania “living in the dirt.”


This Spring, Jeff won the Hog’s Hunt 50k in an exciting little race at the front.
