Pre Run Sodium Timing
Pre run sodium timing front-loads salt before long hot runs for heavy sweaters—test at breakfast and final-hour sips in training, not first on race day.
Pre run sodium timing places salt intake before long or hot efforts so plasma sodium stays stable when sweat losses climb—not a salty feast minutes before a five-kilometer jog. Many heavy sweaters eat a normal salty breakfast three to four hours out, then sip electrolyte drink in the final hour.
Trial in training, not race morning experiments. Pair with fluids; dry salt alone can upset the stomach.
Common questions
-
How much sodium before a long run?
Ranges vary by sweater type—often three hundred to six hundred milligrams in food plus drink in the final hour for heavy sweaters. Sweat sodium testing or guided trials beat copying elite athlete numbers.
-
Can pre-run salt cause bloating?
Yes if timing is too tight or dose is new. Practice the same breakfast and drink rhythm on long training days before race morning.
