BIG THANK YOU to all 300+ people who answered my question, “What more content would you like to see in this newsletter, on the Extramilest Podcast, and on my YouTube channel?” (Congrats Paul Knight for winning the $200 gift card from PathProjects.com)
The most requested content was more videos featuring recreational, non-elite runners, as they offer relatable experiences and inspiration to other runners. There were also several requests for specific training tips, racing strategies, elite interviews, and insights from movement and fitness experts.
Today I’m happy to share the a new Extramilest Show with a recreational runner:
“My heart rate is low, I’m not even running in any kind of strained way, I’m completely relaxed, and yet I’m just killing it, I’m crushing it, so imagine what you can do in a race situation.” – William Barth on Extramilest Show #92
William Barth, a passionate recreational runner from Los Angeles, Boston Marathon qualifier, and advocate for mindful running, shares his transformative journey of overcoming injuries, embracing zone 2 / MAF low-intensity training, and finding joy in consistency and intentional living.

A few quotes from Extramilest Show #92 by William Barth:
- “Fueling is critical, and even though we know it and practice it, I wasn’t doing it enough, and it made a big difference once I corrected that.”
- “Aerobic development takes time, and getting all the different elements dialed in correctly makes a massive difference in the overall race experience.”
- “The idea was to build wealth, to get richer by longer, slower running, and that’s, in a nutshell, sort of the basis of the method.”
- “You have to strengthen your body or you’re going to get injured. There’s just no way around it.”
Cheers,

P.S – It has been 6 months since completing the World Majors and I’m still wearing those 7 medals all day long. The cow bell sound it makes drives my family and neighbors nuts :) Have fun out there on your runs!
