Understanding Running Intensities andTheir Hydration Demands

Running intensity is typically categorized by pace, heart rate, and perceived exertion. Each intensity zone imposes different fizjological stresses and fluid losses, which chich in turn dicte specific hydration tactics.

Sodium loading the pre- run meal (np., pretzels, a hydration tablet, or a pinch of salt in water) helps setalin fluid andd stymulates through. For runners who are hevy salt sweaters (visible salt crystals on skin), this step is especially critical.

Knowing thee theory is on e thing; executing a hydration plan on thee road or trail requires practice andd flexibility. The following strategies will help you bridge thee gap between knowledge andd action.
