"Athletics" covers a wider range of physical demands than almost any other youth sport — a 100m sprinter, a 1500m runner, and a long jumper are training completely different energy systems, even though they might compete at the same meet. That range means athletics nutrition benefits from being tailored to event type rather than treated as one blanket approach. This guide covers training-day and meet-day nutrition across sprint, distance, and field events for young athletes ages 6-16, sourced from UK government dietary guidance.

Sprint and power events (100m-400m, jumps, throws)
Sprint and field events rely heavily on short, explosive effort rather than sustained endurance, which shapes the nutrition priorities slightly differently from distance running. A carbohydrate-and-protein meal 2-3 hours before training or competing (rice with chicken, pasta with a lean sauce) supports both the explosive effort and the strength/power development that underpins these events — see our Build Strength guide for more on the nutrition side of power development. A light carbohydrate top-up in the hour before competing, plus steady hydration, rounds this out. Because these events are typically over quickly, in-event fuelling isn't usually a factor — the emphasis is on being well-fuelled going in.
Middle and long-distance events
Distance events place a greater demand on sustained carbohydrate availability, making the pre-event meal and, for longer events or a demanding meet schedule, in-event fuelling more relevant than for sprint events. A carbohydrate-focused meal 2-3 hours beforehand, familiar and easily digested, remains the foundation. For younger age groups, distances are generally short enough that in-race fuelling isn't necessary; for older teens moving into longer distances, water (and for genuinely extended efforts, a diluted carbohydrate drink) becomes more relevant, though this is the exception rather than the rule at youth level.
Meet-day nutrition: managing multiple events and long gaps
Athletics meets often involve a young athlete competing in multiple events across several hours, sometimes with long, unpredictable gaps between them depending on how the schedule runs — closer to a swimming gala or rugby festival than a single football match. A light, carbohydrate-focused meal 2-3 hours before the first event, then small, easily-digested snacks between events (a banana, a cereal bar, diluted juice) rather than a large meal, works well. Steady water intake through the day is essential, particularly at outdoor meets with no guaranteed shade and long periods of waiting between events. Plan snacks and water for the whole day in advance rather than assuming there'll be time to sort it out between events.
Recovery after training and meets
The 30-60 minute window after a hard session or a meet is when the body is primed to begin refuelling — a combined protein-and-carbohydrate snack or meal (chocolate milk, a sandwich, a yoghurt with fruit) supports recovery well, particularly important after a multi-event meet day where cumulative fatigue is higher than a single race would cause. Continued hydration through the rest of the day, not just immediately after finishing, matters especially at outdoor meets in warm weather.
Girls in athletics
Iron matters more in athletics than in almost any other youth sport, because it does the job athletics asks for — carrying oxygen to working muscle.
From around 12, once periods begin, the reference intake rises to 14.8mg a day against 11.3mg for boys. In an endurance event that difference is directly visible in performance: low iron means less oxygen delivered, which means slowing in the back half of a race and a recovery that takes longer than it used to. It is routinely mistaken for a training problem.
Red meat two or three times a week, lentils, beans, fortified cereals and dark greens, always paired with a source of vitamin C to improve absorption.
Worth a GP conversation rather than guesswork: unusual tiredness despite sleeping well, recovery between sessions getting slower, performance dipping without an obvious reason, looking pale, or concentration dropping off. Any of those in a girl in regular training is worth an iron test before it gets put down to fitness.
Energy needs differ from the boys' figures too, and those are set out by age on our nutrition by age guides.
And never restrict. A girl in regular training needs more food, not less, and eating too little to cover both training and growth affects bone development, energy and injury risk. If periods become irregular or stop, that is a signal to see a GP — not something to train through.
Common mistakes
Applying the same fuelling approach to a sprinter and a distance runner. The energy demands are different enough that a one-size-fits-all routine underserves one or both — tailor pre-event nutrition to the specific event type your child competes in.
Under-planning for long gaps between events at a meet. Multi-event meet days need the same between-event snack planning as a swimming gala or rugby festival — don't assume a single pre-meet meal will carry a child through several hours of competing and waiting.
Underestimating outdoor meet conditions. Long periods standing or sitting in the sun between events, often with limited shade, increase hydration needs beyond what the competing itself would suggest.
Skipping recovery nutrition after a multi-event day. Cumulative fatigue across several events adds up even if no single event was especially long or hard — treat a full meet day's recovery needs as greater than a single race's.

Frequently asked questions
Do sprinters and distance runners need different nutrition? Yes, to a degree — sprint and power events rely on short, explosive effort and benefit from a strength-supporting diet, while distance events place more emphasis on sustained carbohydrate availability. Both share the same core pre-event meal principles, just with slightly different emphasis.
How should my child eat at an athletics meet with multiple events? A light, carbohydrate-focused meal 2-3 hours before the first event, then small snacks like bananas or dried fruit between events rather than large meals, with steady water throughout — especially important at outdoor meets with long gaps between events.
Does my child need to eat or drink during a race? For most youth-level events, no — races are typically short enough that being well-fuelled beforehand is sufficient. In-race fuelling becomes relevant only for older teens competing in genuinely extended distance events.
Why does my child seem extra tired after a full meet day compared to training? Cumulative fatigue across multiple events, plus often long periods standing or waiting outdoors, adds up even without any single very hard effort — treat meet-day recovery nutrition as more important than a single training session's.
What should my child eat before a field event like long jump or throwing? The same principles as sprint events — a carbohydrate-and-protein meal 2-3 hours beforehand supports the explosive power these events rely on.
