S2E18. What happens to your body at 8,000 ft (2,500m)?

This week on Race Ready, Andy checks in from one of the most unique training environments in North America: the Haig Glacier in Alberta. With athletes hiking nearly an hour just to reach the snow and training above 8,000 feet, the conversation dives into how to structure a productive volume camp without turning it into a survival contest. Andy and Brian break down how much to increase training volume, why consistency matters more than one massive week, and how to keep easy training truly easy.From there, the episode becomes a deep dive into altitude training. They discuss what happens to the body during the first 24–48 hours at altitude, why the first two days should usually be kept easy, how long it takes to create meaningful altitude adaptations, and how athletes should approach racing at elevation when they can't arrive weeks in advance. The conversation also covers how intensity should change at altitude and why the goal is often to let the physiological adaptation do the work rather than forcing hard sessions.Andy and Brian also take on the Zone 2 training debate, using Johannes Klæbo's training philosophy as a jumping-off point to discuss why more moderate-intensity work is not always better for high-volume endurance athletes. They finish with practical lessons on technique, fueling, hydration, recovery, and why getting hungry during a long training session may already mean you've waited too long to fuel. It's an episode packed with useful takeaways for any endurance athlete trying to train more, recover better, and make big training blocks actually count.
