He flew across the world, navigated a high-stakes visa process, got sick right before travel, and still walked away with a breakthrough weekend. We’re back with mountain running standout Kieran Nay, fresh off the WMRA World Cup in China, where he delivers a top 15 in the uphill and a top 10 in the Mountain Classic, including the surreal experience of racing on the Great Wall.

We talk through what WMRA events feel like on the ground: the organization, the media presence, and why Kieran values the series’ anti-doping focus. From there, we zoom out into the bigger trail running conversation: WMRA vs Golden Trail vs skyrunning, the push and pull between private series and federations, and whether the sport should ever try to unify under one umbrella. Along the way, Kieran shares what it’s like standing out in a new culture, troubleshooting payments with WeChat, and seeing how sport can cut through the easy narratives we tell about other countries.

Then we get practical. Kieran breaks down pacing, heart rate, and decision-making for steep VK-style efforts, plus what changed for him on technical downhills in the Mountain Classic. We dig into training in Gunnison, grade specificity, heat prep, and the mental shift that helps him race with curiosity instead of pressure. We also hit altitude tools, respiratory muscle training, and his interest in experimenting with bicarb and other marginal gains as the season ramps toward Broken Arrow, SeirSandal, Grand Traverse, and the Pikes Peak Marathon.
