#154 - Mason Coppi

Send us Fan MailWhat does it take to race on the edge, fix your flaws, and build a season that holds up under pressure? We dive deep with Mason Copi, fresh off a blistering run at the World Mountain and Trail Running Championships and a domestic campaign that turned him from underrated to undeniable. Mason opens up about starting fast when the course rewards it, working the early road section, and the moment when cramps hit yet belief held. You’ll hear how teammates on the course and a fired-up Team USA on the sidelines fueled each surge and why chasing the podium sometimes means accepting the crash.Then we get practical. Mason breaks down how he transformed downhill running from a fear response into an advantage using exposure reps on technical segments and a simple “monster truck” form cue. He shares the training blueprint that keeps him healthy while racing often: threshold work for speed and lactate clearance, high aerobic volume buffered by the bike, and minimalist strength focused on hips, glutes, calves, and soleus. No fluff, no gimmicks—just the boring, repeatable work that lets you push hard again next week. We also explore how rising U.S. depth—think Taylor, Cam, Christian—lifts everyone, turning rivalry into fuel.Looking ahead, Mason maps an ambitious 2026: sharpening for the USATF Half in Atlanta, testing range at the Boston Marathon, mixing mountain classics like Big Alta and Gorge, and stepping into the unknown at Speedgoat 50K to build muscular endurance and dial nutrition. He’ll chase a WMRA team spot at Sunapee and aim for an Olympic Trials qualifier at CIM, answering the bigger question of how fast a sub-ultra mountain runner needs to be now. We close with a candid look at free agency—why sponsorship timing is tricky, what autonomy enables, and how to keep betting on yourself when the budget says camp and the goals say compete.If this conversation moved you, follow the show, share it with a friend who loves mountain running, and leave a quick review so more listeners can find these stories.
