264. Running Hydrated: Mastering Fluids & Electrolytes

What this episode covers

With summer weather upon us in the Northern Hemisphere, this episode of the Marathon Running Podcast tackles the hot topic of hydration and electrolytes for runners. Host Letty chats with registered dietitian Serena Marie, RD (@runnergirldietitian on Instagram), to break down hydration basics and individual needs, including recognizing dehydration and tailoring fluid intake based on sweat rate, weather, and intensity, while also exploring the "drink to thirst" versus planned hydration strategies. They delve into the connection between hydration and gastrointestinal issues, offering advice for sensitive stomachs and pre-race adjustments. The conversation then shifts to key electrolytes for runners, when replacement is truly necessary, practical replenishment methods beyond sports drinks, and guidance on navigating electrolyte supplements. Finally, Serena and Serena discuss the crucial relationship between hydration and electrolyte balance, common misconceptions, actionable tips for better hydration, and strategies for practicing hydration during training for longer races.Serena is @runnergirldietitian on instagram!
