Nutrition fundamentals for teenage runners balancing school, training, and growth.
Adolescent runners face:
| Factor | Impact |
|---|---|
| Growth | Additional 500-1000+ calories vs. adult |
| Training | Additional 300-800+ calories depending on volume |
| Total needs | Often 2500-4000+ calories/day |
The traditional high school schedule is actively hostile to endurance nutrition. You must force food into the gaps.

title Navigating the Adolescent Fueling Gaps
06:00 AM (Wake Up) : The Pre-Load : Something small before the bus (Toast, Banana, or Waffle). Never start empty.
10:00 AM (Passing Period) : The Bridge : A 300kcal snack between 2nd and 3rd period to stop the blood sugar crash.
12:00 PM (Lunch) : The Main Engine : A massive mid-day meal. Not just snacks. You are fueling the 3:00 PM workout right now.
02:30 PM (Final Bell) : The Top-Off : 150kcal of simple carbs directly before lacing up the spikes.
05:00 PM (Post-Practice) : The Golden Window : 20g of Protein + Carbs (Chocolate Milk) before getting in the car to go home.
07:00 PM (Dinner) : The Rebuild : A heavy, balanced meal. The body repairs bone and tissue overnight using this food.
Upon waking (if anything):
After practice/Before school:
Pre-practice snack (if needed):
Post-practice:
| Choose | Avoid (Most Days) |
|---|---|
| Meat/protein options | Deep-fried everything |
| Starch (rice, pasta, bread) | Only junk food |
| Fruit and vegetables | Skipping lunch |
| Milk or water | Just soda |
| Category | Examples |
|---|---|
| Quick carbs | Granola bars, pretzels, fruit |
| Protein + carb | Cheese + crackers, yogurt, PB + apple |
| Portable | Bars, trail mix, fruit |
| Nutrient | Why |
|---|---|
| Calcium | Peak bone mass window (can't make up later) |
| Iron | Menstruation + running |
| Vitamin D | Bone development |
| Overall energy | Hormonal health |
[!WARNING]
RED-S Clinical Red Flags
If a female athlete presents with any of the following, the coaching staff and parents must intervene immediately:
- Amenorrhea: Missing 3+ consecutive periods (this is never "normal" for running).
- Bone Injuries: Multiple stress reactions or a full stress fracture.
- Developmental Stalling: Falling off their pediatric growth curve.
- Unexplained Fatigue: Constant lethargy that does not improve with rest days.
6:30 AM: Toast + peanut butter + milk
10:00 AM (snack): Granola bar
12:00 PM (lunch): Turkey sandwich, apple, yogurt, water
3:00 PM (pre-practice): Banana + crackers
5:30 PM (after practice): Chocolate milk
6:30 PM (dinner): Chicken, rice, vegetables, salad
9:00 PM: Cereal + milk
