In this episode, I’m sharing my Boston Marathon experience from Hopkinton to Boston. Then we’re diving into the science of fueling and hydration — specifically, electrolyte depletion: what it is, why it matters for performance, and how you can stay ahead of it. Whether you’re training for your first marathon or refining your race-day strategy, this episode is packed with practical tips to help you feel strong, stay balanced, and go the distance.
