Quick start
Start here
Nutrition fundamentals for teenage runners balancing school, training, and growth.
Daily structure
Three meals is the floor, not the whole plan
- Most young runners also need a pre-practice snack and a recovery option.
- School lunch counts, so weak lunches often create weak practices.
Before practice
Use simple carbs if the school day ran long
- Bananas, bars, crackers, yogurt, or toast fit well before training.
- Young athletes often say they are fine until the second half of practice proves otherwise.
Hydration
Water bottle habits should be taught, not assumed
- Many adolescent runners arrive at practice already behind on fluids.
- Refill the bottle during school and continue drinking after practice.
1. Eat early
Breakfast does not need to be perfect.
Breakfast does not need to be perfect. It does need to exist.
An adolescent runner who starts the day empty usually spends the whole day trying to catch up.
- toast and peanut butter
- cereal and milk
- yogurt and fruit
3. Put fuel around practice
Before practice:
simple carbs work well
banana, crackers, applesauce, pretzels, granola bar, or toast are fine
get carbs plus protein in within the first hour
chocolate milk, yogurt plus fruit, sandwich, cereal and milk, or leftovers all work
A practice-day template
Here is a simple structure that works for a lot of teenagers:
Breakfast
carb plus protein plus fluid
Mid-morning
snack if lunch is late
Lunch
real meal, not just chips and a drink
Pre-practice
easy carbs
Post-practice
carbs plus protein

RED-S Warning Signs and Prevention
If female-athlete fatigue is part of the picture: Iron Deficiency in Female Runners
Colorado and altitude change the picture
If you train in Colorado or anywhere around 6,000 feet and up:
If you train in Colorado or anywhere around 6,000 feet and up:
At altitude, the margin for under-fueling gets smaller. A pattern that might be merely sloppy at sea level can turn into poor recovery, heavy legs, headaches, or iron problems faster.
- fluid needs are higher
- carbohydrate needs can feel higher because training stress is higher
- iron status deserves more respect, especially in female athletes or runners with a fatigue history

Carbohydrate
Carbs are not optional for runners.
Carbs are not optional for runners. They are the main fuel source for training, recovery, and school-day energy.
