    Do you know your sweat rate? Or how much sodium you should be replacing as the weather gets hotter? That's what today's episode is for!

    This week, Corinne Malcolm and Keely Henninger dive into all things hydration as the season and the sun heats up. They break down:

    • Osmolality and what it means for training and racing
    • How to do some basic sweat testing at home
    • And, of course, balancing hydration with carb intake and fueling!
