But the real reason people quit has nothing to do with their legs. In this episode, I break down the neuroscience of why your brain calls it quits long before your body actually has to, including Tim Noakes' Central Governor Theory, Huberman's research on the anterior mid-cingulate cortex, and what Goggins' 40% rule actually looks like in practice. You'll walk away with real, research-backed mental strategies you can use the next time everything in you wants to stop. This is Episode 8 of my Swiss Alps 100 series. If you're new here, check out the full playlist. Hope you enjoy! What does it actually take to run 100 miles through the Swiss Alps? This 20-episode series follows my full journey, from the first training run to the start line in Switzerland. Every long run, every setback, every gear decision, and every doubt along the way. No highlight reel. Just the real process of preparing for one of the most demanding ultramarathons in the world.
