Marathon Sodium Strategy
A marathon sodium strategy schedules electrolytes for sweat and heat—rehearsed in training, not improvised from aid-station fear or salt myths.
A marathon sodium strategy plans electrolytes across race week and race day—salty training fluids in heat, pretzels or broth if you are a heavy sweater, and drink mix on course aligned to sodium-per-hour targets. It is not random salt pills.
Kidney disease, hypertension, and certain meds need clinician guidance.
Common questions
-
Should every marathoner salt-load the day before?
Heavy sweaters in heat often benefit from modest sodium emphasis; cool events and low sweaters need less. Personal sweat patterns and clinician advice beat copying elites.
