Hydration is not a contest to replace every millilitre of sweat. Start normally hydrated, learn your personal response and avoid drinking beyond what you lose.

THE GTGF KNOWLEDGE STANDARD
We write for athletes who want to understand what they are doing. Every new article therefore includes a concrete learning goal, practical actions, common mistakes, a safety boundary and sources appropriate to the claim.
Consensus statements, systematic reviews and primary sports science take priority. Practical guidelines are identified as such.
A training zone, carbohydrate recommendation or recovery measure always receives context: sport, duration, level, conditions and individual response.
After the mechanism comes what you can actually test, measure or adjust in the coming week.
Health, injury and supplement topics include a clear boundary where general sports information ends.
