The Fargo and Sioux Falls marathons are fast approaching, and in preparation runners are out logging hundreds of miles on the roads and trails.
As the mileage increases and runners hit the peak weeks of their training, nutrition becomes increasingly important. Despite this, many endurance athletes may not be eating enough calories to support that training and can end up disrupting their training.
Being able to recognize some of the common signs of under-fueling and how to improve nutrition can help runners get the most out of their training, and meet their performance goals this race season. Learn more from Sanford Health diet and nutrition experts.
Eating enough
If a runner is under-fueling, they might feel fatigued (that “dead legs” feeling) during or after runs, not able to hit their goal paces, have a hard time recovering after runs, experience unintended weight loss, and may have a higher risk of injuries. Some runners may feel hungry all day, or find themselves thinking about food or thinking about certain foods (craving carbohydrate or protein-rich foods) all day long.

There can be more going on than just not eating enough if a runner is feeling fatigued/tired all the time or if they have an inability to hit their training paces (for instance, iron deficiency could be at play), so runners should always contact their physician if they troubleshoot their nutrition and suspect there’s more going on.
Signs runners may be not eating enough, intentionally or unintentionally, to fuel their mileage:
- Not aware of their energy needs with an increase in mileage, and not changing portion sizes or meal timing to accommodate those calories
- Unintentionally not eating enough by trying to eat healthy during training
- Decrease in appetite from an increase in mileage or from intense workouts
- Intentional reduction in portion sizes/snacks to lose weight during training
Extra meals or snacks
Runners need fuel during training. A runner logging 50 miles a week is burning, on average, 80-100 calories per mile (over 500 extra calories per day) on top of what they usually eat to maintain their weight.
To meet those needs, runners can add extra pre- and post-workout recovery fuel, long run fuel and hydration products, and larger portions at meals or extra snacks during the day.
Runners who just don’t feel like eating can try eating smaller portions, more frequently (four smaller meals instead of three large meals), adding extra mini-meal snacks, or sipping on their calories in the form of fruit smoothies.
While weight loss isn’t impossible during training, it is not recommended if training for a performance/time goal is the main goal. Logging all those miles requires plenty of calories (energy) to train, build muscle, and recover, and without enough calories to support those activities, training may suffer.
Basic rules
To get the most out of your training, read these “rules of thumb” for fueling this racing season:
- Don’t skimp on the meals surrounding training runs, especially post-workout recovery. Refuel with carbohydrates and protein ASAP after your run.
- Practice race-day nutrition by practicing pre-long-run fueling on long run days.
- Fuel on the run for runs over 90 minutes – take along carbohydrates and fluids.
- Eat when hungry – don’t ignore hunger just because you usually don’t have a snack/meal at that time.
- Practice meal prep or packing meals early on in the training cycle – you’ll be in a routine to choose healthy, balanced meals later in training when you have less time to prepare meals and snacks.
- Carbohydrates are important, but remember to include protein, healthy fats and colorful fruits and vegetables at meals to help make meals more balanced and satisfying.
- Focus on balanced meals – training does increase our energy needs, but eating only high-calorie, low-nutrient foods can also leave you feeling sluggish.
Seek input
If you have a new distance goal, want to set a personal record this year, are experiencing stomach distress or fatigue on runs or have any nutrition questions, working with a sports dietitian can help you dial in your nutrition and create a plan to help you meet your training and performance goals.
