Hydration planning combines drinking-water access, carrying capacity and a manageable route. One fixed hourly amount cannot fit every person and condition.
Keep drinks reachable
Choose bottles or a reservoir you can use without a lengthy unpacking stop. Check closures and leaks beforehand. Agree confirmed refills and a fallback if a source is unavailable. Carrying capacity and actual supply are separate questions.
Do not force a formula
Needs vary with effort, conditions and individual circumstances. Avoid both ignoring thirst and forcing excessive water to meet an arbitrary target. Seek clinical advice if a medical condition affects your fluid plan.
Change the day when necessary
Reduce exposure and tell the guide promptly if someone feels unwell. Read the heat-illness guidance and the Atlas water-planning guide. A shorter appropriate route is better than trying to solve every heat problem by adding drinks.
