#182 - Marshall Graybill

Send us Fan MailYou can learn a lot about mountain running by talking to someone who didn’t grow up logging endless run miles. Marshall Graybill comes to the sport through cycling and ski mountaineering, with all the fitness those sports build and all the baggage they can bring, too. We get honest about what it feels like to line up for a race after crashes and concussions, how fear shows up in specific scenarios, and why trail running can feel like a mental reset compared to crit racing chaos. Marshall also lives a double life that a lot of driven athletes will recognize: he’s deep into a PhD focused on underwater robotics, studying alternative propulsion inspired by marine organisms. That time pressure forces a different training mindset, and we talk about how to stay competitive with shorter, harder sessions, how to avoid the Strava comparison trap, and how to pick races that fit real life. If you’re chasing endurance performance with limited hours, this one is packed with relatable strategy. We also swap stories from skimo culture in Colorado, the intensity of local “world cup” style races, and the frustrating reality of canceled events and narrow qualification paths now that skimo is an Olympic sport. Then we jump to Marshall’s surprise 25K win at the Waterville Trail Running Festival in Ireland, where navigation, farm crossings, and under-flagged trails turn a race into a problem-solving mission. We wrap with Broken Arrow plans, pacing lessons at altitude, and why the community keeps bringing him back. If you enjoy conversations on trail running, mountain running, skimo training, altitude racing, and balancing sport with a demanding career, subscribe, share this with a training partner, and leave a review with your biggest takeaway.Follow Marshall on IG - @marshallgraybillUse code SteepStuff for 20% your cart on Sidas.usFollow James on IG - @jameslaurielloFollow the Steep Stuff Podcast on IG - @steepstuff_podFollow Sidas USA on IG - @sidas_usa
