Caffeine + fluid
Caffeine &
Hydration
Caffeine does not automatically dehydrate athletes, but dose, timing, heat, and total fluid still change how the plan should work.

Caffeine hydration reality
Caffeine works best when athletes know what they will take, when they will take it, and what the fluid plan looks like before and around it.
Race-plan checklist
Before race day
dose, source, and timing already tested
Caffeine plan includes a fluid plan beside it
Heat block
extra attention to gut response and pre-session hydration
Baseline hydration habits solved before chasing caffeine theory
Coach cue
ask what the athlete will drink before and with the caffeine source
What coaches misread
Caffeine does not erase the need for baseline hydration earlier in the day.Improvised caffeine on race day often creates more problems than value.High doses, heat, and a nervous stomach raise the downside quickly.
Ask the athlete what they will drink before and with caffeine instead of debating caffeine in the abstract.
