Special considerations for teenage female runners during growth and development.
Growth plus sport
Teen athletes need enough food for training and for normal development
- Puberty, menstrual development, bone growth, and school-day demands all add to the total load.
- Underfueling during adolescence can change the entire health trajectory, not just the next race.
School-day problem
The biggest misses usually happen between first period and practice
- Skipped breakfast, weak lunches, and no afternoon snack leave the athlete trying to train on fumes.
- School and commuting schedules make portable fuel non-negotiable.
Priority nutrients
Calcium, vitamin D, iron, protein, and enough total energy deserve consistent attention
- These nutrients interact with growth, bone health, blood health, and recovery.
- Teen girls who train hard often need more deliberate planning than adults around them realize.
Warning signs worth watching for
One rough week is not a diagnosis.
Missed or irregular periods after previously regular cycles
Performance sliding without a clear training explanation
Repeated stress reactions, stress fractures, or nagging shin pain
Fatigue that does not match the training plan and does not improve with rest
Growing food fear, skipped meals, or rigid rules around eating
Start with the real problem: not enough fuel, not too much
The most common nutrition issue in teenage female runners is not overeating or "bad" food choices.
The most common nutrition issue in teenage female runners is not overeating or "bad" food choices. It is under-fueling, which sports medicine calls low energy availability: not enough energy left over for normal body function after training is paid for.
When intake does not keep up with training plus growth, the body starts conserving. Reproductive hormones drop, bone building slows, recovery drags, and eventually performance stalls. This is the core of what the IOC now calls Relative Energy Deficiency in Sport, and it affects health and performance across every…
So the first coaching question is almost never "is she eating too much?" It is "is she eating enough, often enough, to cover school, training, and growth?
Watch for
What to watch before it becomes a crisis
Performance drop-offs, stress injuries, menstrual disruption, and persistent fatigue rarely show up as isolated issues.
- Under-fueling is often quieter than coaches expect.
- The best first move is usually a food-plus-screening conversation, not a supplement guess.
- Parents and coaches should hear the same short message.

If fatigue and heavy legs keep showing up, screen iron early: Iron Deficiency in Female Runners
The nutrients that deserve extra attention
For general training fuel, carbohydrate does the heavy lifting and protein spread across the day supports recovery and growth (Thomas 2016).
For general training fuel, carbohydrate does the heavy lifting and protein spread across the day supports recovery and growth (Thomas 2016). A few nutrients matter more for this specific group.
Iron. Female runners lose iron through menstruation, and endurance training adds more demand. Low iron is a common, treatable cause of unexplained fatigue and declining workouts. If a runner is dragging, testing iron status is more useful than guessing. Do not start iron supplements on your own, because too much iron…
Calcium and vitamin D. Adolescence is the window when most lifetime bone is built, so it is the worst time to be short on the raw materials. Food-first is the goal, with calcium in the range of roughly 1,300 mg per day for teens spread across meals. Vitamin D is harder to get from food and is worth a clinician's…
Altitude raises the stakes
For teams training around 6,000 to 7,000 feet in Colorado, the margin for under-fueling gets thinner.
For teams training around 6,000 to 7,000 feet in Colorado, the margin for under-fueling gets thinner. Fluid needs run higher, training stress is higher so carbohydrate needs feel higher, and iron status deserves more respect, especially in female runners with any fatigue history. A fueling pattern that would merely…

Main reality
Growth costs energy too
Treat this as a decision anchor, not a trivia stat.

Coach takeaways
Use this with athletes
These are the cues worth repeating before the week gets busy.
Feed growth
Teen athletes are paying both a training bill and a development bill.
Protect school hours
Portable breakfasts, lunches, and snacks matter more than motivation speeches.
Coach language
Normalize eating enough as part of being serious about sport.
What to do next
