Coach Caroline and Coach Valerie delve into one of the biggest summer training challenges for runners: staying hydrated when the heat and humidity intensify. The conversation starts with a real-world Texas problem, where even gardening can leave you feeling overworked, discombobulated, and dealing with gut issues hours later. Valerie explains why it is important to test yourself, because everybody sweats differently and you cannot assume your hydration needs are the same as someone else’s.

This episode breaks down practical ways to figure out what your body actually needs. Valerie walks through a simple weight test, explains how much fluid she personally drinks during a morning of workouts, and talks through why hydration is not just about water alone. The episode also covers the difference between carbohydrates and electrolytes, why salt alone is not enough, how to look for a product that includes magnesium and potassium, and why the best strategy is to pre-hydrate instead of waiting until you feel bad.

Valerie also explains that hydration gets more important as you get older, just like warm-up and recovery do. The episode closes with practical planning tips such as stashing bottles, finding fountains, and using a “hydrate prep” mindset before long runs or hot days outdoors. If you want to ask a question, the team invites listeners to leave it on YouTube, where they will answer it in a deep dive, a shorter video, or on the podcast.
