Buckle up! This week, Coach Brian and Mandy Mullen sit down with Chris Avery, a man who went from "accidental runner" to planning one of the most ambitious physical feats we’ve ever heard on the show.

Chris shares the story of how a spur-of-the-moment marathon with zero training ignited a fire that hasn’t gone out since. Now, he’s preparing for his biggest "why" yet: running the entire perimeter of the United States in 2027 with his family by his side.

In this episode, we discuss:

• How a "run every day" streak can shift your entire identity.

• The 2027 Challenge: Why Chris is taking his family on a journey around the edge of the country.

• The mental grit required to lead by example for your children.

• Why "starting small" is the only way to achieve something massive.

In this episode of Buckle Up, Coach Brian and Mandy Mullen sit down with the renowned Dr. Jason Karp to discuss the intersection of sports science, culture, and technology. Dr. Karp takes us through his fascinating journey from a curious student of human anatomy to a leader in the running community.

The conversation dives deep into his time coaching in Kenya, revealing how a culture rooted in community and hard work shapes world-class athletes. Dr. Karp also opens up about his latest innovation, RunKasi, an AI-powered coaching app designed to bring real-time, expert guidance to runners everywhere. From the nuances of women’s physiology to the future of remote coaching, this episode challenges the status quo of the running industry.

This week, we sit down with Ellie Martinez, the essential "right hand" to our co-host Mandy Mullen. We go behind the scenes to discuss Ellie’s pivotal role at Run.Windsor and what has surprised her most about working in the industry. Plus, Ellie opens up about her lifelong background in sports and draws a fascinating parallel between the patience of hunting and the endurance of ultra running.
