Performance Nutrition Primer

Training only works when athletes are fueled well enough to adapt. This section gives athletes and families practical guidance on food, recovery, hydration, and iron-rich eating habits.

Carbohydrates

Primary training fuel45–60%

Carbohydrates support workout quality, racing, glycogen replacement, and recovery.

Protein

Repair & adaptation20–30%

Protein supports muscle repair, immune function, recovery, and adaptation.

Healthy Fats

Hormone support20–30%

Healthy fats support hormone production, vitamin absorption, joint health, and long-duration energy needs.

General Calorie Guidelines for High School Runners

Calorie needs vary by body size, event group, mileage, growth, metabolism, sleep, and stress. These ranges are rough guidelines, not strict targets.

Athlete TypeEstimated Daily CaloriesNotes
Smaller developing runner2200–2800 kcalYounger athletes or lighter runners with moderate training loads.
Typical high school distance runner2800–3800 kcalCommon range during active cross country or track seasons.
High-mileage varsity runner3500–5000+ kcalEspecially during peak mileage or championship training blocks.
Sprint / power athlete2600–4200 kcalNeeds vary with body size and strength training volume.
A high school runner training hard 6–7 days per week is not nutritionally comparable to a sedentary teenager.

Iron and Athletic Performance

Iron is essential for oxygen transport, red blood cell production, aerobic metabolism, and recovery. Low iron availability can contribute to fatigue, elevated heart rate, poor workout recovery, declining endurance, dizziness, headaches, and difficulty maintaining training quality.

Distance runners, female athletes, rapidly growing athletes, and high-mileage runners are at greater risk for iron deficiency. Nutrition matters long before an athlete reaches clinical anemia.

Iron absorption is not equal across foods. Heme iron from animal sources is generally absorbed much more effectively than non-heme iron from plant sources.
Food SourceIron TypeRelative BioavailabilityNotes
Clams / oystersHemeVery highAmong the most absorbable natural iron sources.
Liver (beef or chicken)HemeVery highExtremely iron dense, though not universally popular.
Red meat / bisonHemeHighExcellent athlete-friendly iron source with strong absorption.
Dark turkey meatHemeModerate-highGood option for athletes who avoid red meat.
EggsMixedModerateUseful support food, though less absorbable than red meat.
Lentils / beansNon-hemeModerate-lowAbsorption improves when paired with vitamin C.
SpinachNon-hemeLowerContains iron, but also compounds that reduce absorption.
Fortified cerealsNon-hemeVariableCan help intake totals, but absorption varies widely.

Improving iron absorption: pair iron-rich meals with vitamin C sources like tomatoes, citrus, peppers, or berries. Avoid consuming large amounts of calcium immediately alongside iron-focused meals when possible.

Featured Team Meal — Bison Chili

This meal combines highly bioavailable heme iron from bison with vitamin C-rich tomatoes, fiber-rich beans, and additional micronutrients from spinach.

IngredientAmount
Ground bison2 lb
Dark red kidney beans2 cans, drained
Diced tomatoes2 large cans
Tomato paste1 small can
Fresh spinach1 large bag
Yellow onions2 diced
Bell peppers2 diced
Garlic4–6 cloves
Beef broth2 cups
Chili powder2–3 tbsp
Cumin1 tbsp
Smoked paprika1 tbsp
Salt & pepperTo taste

Preparation

  1. Brown the bison in a cast iron pot or Dutch oven to increase iron transfer during cooking.
  2. Add onions, peppers, and garlic. Cook until softened.
  3. Stir in tomatoes, tomato paste, beans, broth, and seasonings.
  4. Simmer slowly for 1.5–3 hours, stirring occasionally.
  5. Add spinach near the end so it softens without overcooking.
  6. Serve with rice, potatoes, bread, or tortilla chips depending on athlete energy needs.
This meal works well after long runs, winter training sessions, and meet weekends because it supports recovery, glycogen replacement, hydration, and iron intake simultaneously.
