Sodium Loading for Runners

Sodium loading for runners raises sodium before hot long events to support hydration and reduce hyponatremia—separate from carb loading and needs medical caution.

Sodium loading for runners increases dietary or drink sodium before long hot events to support fluid retention and reduce hyponatremia risk—distinct from carb loading. Salty broths, pretzels, or electrolyte drinks the day before can help heavy sweaters; kidney or blood-pressure conditions need clinician guidance.

Do not confuse sodium with table salt bingeing without fluids.

Common questions

  • Is sodium loading the same as salting every meal?

    Targeted increases around hot endurance events differ from chronic high salt diets. Personal sweat rate and health history should guide the plan.
