Sub-4 Miler to Black Canyon 100K: The Zach Perrin Story

from Free Outside · host Jeff Garmire

Zach Perrin has run 3:59 for the mile, then promptly got humbled by his first trail race in road shoes and swore he would never do it again. Now he is all-in on ultras, dialing sweat rate and sodium, and lining up at Black Canyon with a golden ticket on the mind. We talk sub-4 race strategy, the “panic point” in the mile, ego-check moments on the trails, and what it actually takes to run well for seven to eight hours.Follow Zach online: https://www.instagram.com/zach_perrin/Chapters 02:00 What a Sub-4 Mile Actually Feels Like05:00 The Mile’s Panic Point vs Ultra Pain08:00 From Montana to CU and Early Running Roots12:00 Leaving Track and Finding the Trails16:00 Getting Humbled in His First Trail Race20:00 Letting Go of Pace Ego and Learning Effort26:00 Fueling, Sweat Rate, and Fixing 100K Mistakes33:00 Adam Peterman, CU, and Training With the Best40:00 Black Canyon 100K Strategy and Golden Ticket Goals52:00 Staying Calm, Mental Approach, and What’s NextSupport our Sponsors: Sawyer: https://sawyerdirect.net/Janji (code: Freeoutside): https://snp.link/a0bfb726CS Coffee: CSinstant.coffeeGarage Grown Gear: https://snp.link/db1ba8abSubscribe to Substack: http://freeoutside.substack.comSupport this content on patreon: HTTP://patreon.com/freeoutsideBuy my book "Free Outside" on Amazon: https://amzn.to/39LpoSFEmail me to buy a signed copy of my book, "Free Outside" at [email protected] the movie about setting the record on the Colorado Trail: https://tubitv.com/movies/100019916/free-outsideWebsite: www.Freeoutside.comInstagram: thefreeoutsidefacebook: www.facebook.com/freeoutside#Trailrunning #Runningnews #Outdoors #Outdooradventure
