Color read
Pale yellow is the goal
- Nearly clear can mean over-drinking.
- Apple-juice yellow means start replacing fluids soon.
Best timing
Check the first pee and the post-session trend
- Morning urine shows how the last day went.
- Post-practice urine shows whether the session beat the plan.
Add context
Match color with thirst, body weight, and feel
- Dark urine plus unusual thirst usually means you are behind.
- A 1-2% body-weight drop confirms meaningful fluid loss.
Morning Pee vs. Post-Practice Pee: Which Matters More?
Both matter, but they tell you different things.
Both matter, but they tell you different things.
Morning urine is your hydration baseline. Dark morning urine means you went to bed dehydrated — either you didn't drink enough the day before, or practice depleted you more than you replaced.
If your morning urine is consistently dark yellow or darker, you have a chronic hydration problem affecting your recovery overnight.
Field use
A field protocol coaches can actually repeat
Morning
Check the athlete before practice starts
Dark urine, headache, and an empty bottle are red flags before the session even begins.
During training
Use planned drinking moments
Scheduled drink breaks beat thirst when the day is hot, dry, or altitude-adjusted.
After practice
Replace losses steadily
Push recovery fluids across the next few hours instead of one rushed bottle.
When Water Isn't Enough: The Electrolyte Decision Tree
Plain water is fine for:
Practices under 60 minutes
Low-intensity activity
Situations where you're well-fed and not sweating heavily
Practice or competition lasts more than 60 to 75 minutes
You're sweating heavily (salty residue on skin/hair after practice)
Printable Hydration Self-Assessment Card
DAILY MORNING CHECK ☐ Morning urine: pale yellow?
Pre-practice
16–20 oz in the 60 minutes before
During (60+ min practice)
6–8 oz every 15–20 minutes
Post-practice
16–24 oz for every pound lost
Long meet days
Drink consistently throughout
At altitude
Add 0.5L/day above your normal target
The Urine Color Chart (The Whole Truth)
Colorless / nearly clear: You might be slightly over-hydrated.
Colorless / nearly clear
You might be slightly over-hydrated. Drinking so much water that your urine has no color at all can dilute your…
Pale yellow (like lemonade)
This is the target. Well-hydrated. You're in good shape.
Yellow (like apple juice)
Acceptable but on the lower end. Drink a bit more in the next hour.
Dark yellow (like apple cider)
You're getting dehydrated. Performance starts to decline. Drink.
Amber or brown
You're meaningfully dehydrated. Performance drops of 5 to 10% or more. Headache, cramping, and fatigue are either…
Red or pink
Call a doctor if this isn't explainable by beets or other red-pigment foods.
Electrolytes Explained Simply
Water gets you halfway there.
Water gets you halfway there. Electrolytes get you the rest of the way.
Sodium — the most important for athletes. Controls how much fluid your blood holds. When you sweat, you lose sodium. Replacing fluid without sodium dilutes your blood — a condition called hyponatremia. Sodium also drives thirst.
Potassium — works alongside sodium for fluid balance inside cells. Found in bananas, potatoes, orange juice. Contributes to muscle cramping when combined with sodium losses.

Coach takeaways
Use this with athletes
These are the cues worth repeating before the week gets busy.
Before school
Aim for pale yellow, not clear.
After practice
Replace losses with fluid plus sodium.
Coach cue
Make hydration a check-in, not a lecture.
