Fueling Your High School Runner: A Practical Nutrition Guide for Parents

Of all the questions parents ask me about their runner, fueling comes up almost as often as training itself, and it's usually followed by some version of "I don't want to get this wrong." So let me lay out what I actually tell the families of the high school runners I coach.

A growing teenage athlete needs more food, not less, and that's the most common mistake I see. A high schooler logging real summer mileage is simultaneously going through normal adolescent growth and development. Restricting food, intentionally or not, during a heavy training block is one of the fastest ways to see performance stall, mood and energy tank, and injury risk climb. If your runner is training hard, this is not the season for cutting anything out.

Breakfast matters more than most families treat it. A lot of teenagers run in the morning or head to practice on an empty stomach out of habit or time pressure. Even something small thirty to sixty minutes beforehand, like toast with peanut butter or a banana, makes a real difference in how a workout feels, especially in summer heat. Skipping breakfast on a training day isn't toughness, it's just leaving performance on the table.

Recovery meals matter as much as the workout itself. The 15 to 60 minute window after a hard practice or long run is when the body is most ready to use protein and carbohydrates to actually repair and adapt. A simple example is chocolate milk, a sandwich, or yogurt with fruit shortly after practice, not skipped entirely because dinner is a few hours away. This is exactly the kind of day-to-day detail I build into the 1-on-1 coaching I do with high school runners, alongside the actual training plan.

Hydration is a daily habit, not a race-day fix. I'd rather see a runner sipping water consistently throughout a hot summer day than trying to make up for it all in the twenty minutes before practice. Teenagers are especially prone to showing up already behind on hydration simply because they got busy and forgot to drink much of anything until practice started.

Watch for signs of under-fueling, not just performance dips. Constant fatigue, getting sick more often than usual, mood changes, or a string of nagging injuries can all be signs that food intake isn't matching training demand, even in a runner who looks like they're eating normally. If you notice this pattern, it's worth a conversation, possibly with a doctor or sports dietitian, rather than assuming it will resolve on its own. If you want a coach's eyes on your runner's overall training and recovery picture, not just fueling, reach out and let's talk.

This is not about strict meal plans or cutting foods out. The teenage runners I coach who fuel well aren't following complicated diets. They're eating real meals consistently, not skipping them under time pressure, and treating food as part of training instead of an afterthought. You can read more about the track record behind this coaching on my about page, fueling and recovery habits like these come up again and again with the families I work with.

If you're a parent trying to figure out how to support your runner's training without overcomplicating things, that's a conversation I have often, and I'm always happy to help point you in the right direction.
