What listeners say

A curated, balanced selection of Apple Podcasts reviews.

No-nonsense deep-dive into the real science behind running. I appreciate the host’s skepticism and wry sense of humor. The back catalogue regarding nutrition and training periodization is particularly helpful for all runners, not just trail amd uktra runners. It’s nice to listen to a non-sponsored podcast where the host isn’t afraid to challenge guests on nonsense!

Mary Pagones · Jun 2024

Great content, specific advise, very practical and useful. Based of proven research, honest and trustworthy advice

NickVashon · Jan 2024

Jason doesn’t hide behind anything and tells it like it is. He never makes talks down to us! I have learned so much from his pod!!

coolingrid · Sep 2023

So much fascinating and useful information. I’m working on educating myself about the newest research on ultra running this year, after years of relying on a coach, and this podcast has been such a fantastic resource.

Patroller gal · Apr 2023

I used to cherry pick some of these episodes and learned some things, however take a listen to episode 161 (2023 preview) before you get too far into this guy’s ecosystem. He aggressively targets other well known coaches and podcasts by name and is quite nasty towards them. One of the things I love about the trail running community is the way we lift each other up, but he unfortunately demonstrates the opposite. It’s fine to have style preferences, but there shouldn’t be any room for this in our sport.

trav&mer · Sep 2023

Interesting guests. It seems like the host wants to move between technical/scientific language and ‘layperson’ language. If so, I respect the intent, but in the process he makes offensive assumptions about the listener, the running community at large. He also makes more accurate assumptions, but the approach is damaging nonetheless. Human intentions are far more nuanced than the way he often paints them (in the four episodes I’ve listened to). Perhaps he will re-evaluate his deep seated stereotypes of the runners and listeners, and instead sacrifice the illusion of hard nosed confidence in order to become a more dynamic and flexible host. Or, perhaps he won’t. I may not stick around to find out.
