How these resources work together. The sweat sodium protocol collects a clean sample for sodium concentration analysis. The sweat rate calculator turns test session data into fluid targets. The race nutrition planner combines both -- plus your product preferences -- into a personalized hour-by-hour race plan. As your training and conditions change, retest and recalculate. Neither sweat sodium nor sweat rate is a fixed number.
