Episode Notes
She’s calling in from the backcountry of Utah with a Starlink connection, fresh off slot canyons, desert miles, and yet another FKT. Erin Tun is back, and our catch-up quickly turns into a deep look at what it actually takes to move fast in the mountains when the air is thin and the consequences are real.
We dig into Erin’s four-month South America push anchored by altitude training in Quito, Ecuador, where repeat climbs and local trail running community support helped set the table for bigger goals. From Cotopaxi and other 5,000 meter peaks to the main objective, Aconcagua, Erin breaks down the real-world mechanics of a fastest known time attempt: scouting versus full summits, choosing lines, managing snow and scree, and why a perfect weather window can disappear overnight. She also describes what performance feels like above 21,000 to 22,000 feet, where “going hard” often means relentless efficiency and not stopping, not running a pretty pace.
From there, the lens widens to the Seven Summits record path, including why Kilimanjaro might be next and what makes an Everest speed record uniquely complicated: oxygen choices, north versus south side routes, political access, permits, and the funding reality behind big peaks. We also talk sponsorship in a way most podcasts skip, including Erin’s move to Tava, her hands-on role testing prototypes, and how building a sustainable career as a modern mountain athlete now includes storytelling, not just results. If you want the behind-the-scenes version of these adventures, Erin and Chris are launching a YouTube channel to show what Instagram can’t.
