As summer heats up and long-distance training intensifies for many of us, maintaining proper hydration becomes more crucial than ever.
In today's episode, I chat with Claire Shorenstein, a sports RD and endurance athlete herself, and the host of the podcast Eat For Endurance, about the essential hydration strategies specifically tailored for runners, especially those tackling the challenges of training in the heat.
We get to know Claire a bit more, and her backstory, and how she got involved in sports nutrition in the first place, and then we dive into hydration before, during, and after runs.
She shares a glaring sign that comes from your gut that tells you that you are not getting enough hydration, and she shares tips to make sure that you aren't drinking so much that you are having to make a bunch of pit stops, and so much more.
Whether you are a seasoned marathoner or runner or just starting your running journey, I know that you are going to gain valuable insights and practical tips on how to stay hydrated on your runs, optimize your performance, and keep your body functioning at its best during these hot running sessions.
