"A pilot study reveals the surprising dietary gaps among long-distance race car drivers and how to bridge them for enhanced performance."


Optimal nutrition is increasingly recognized as a key factor in enhancing athletic performance and recovery. Assessing an athlete's nutritional status helps identify potential problems, fine-tune training adaptations, and ultimately support peak performance. Proper energy intake is vital for maintaining body function and optimizing body composition. During periods of intense physical activity, meeting macro- and micronutrient needs is crucial for maintaining weight, replenishing glycogen stores, and providing sufficient protein for tissue repair. Neglecting these needs can lead to low energy availability and compromise overall health and performance.

Long-distance race car drivers, often considered athletes, face unique physical demands. The sport requires strength, agility, and endurance, particularly during competitions like 24-hour races where drivers endure vibration, high temperatures, and extended driving hours. A single lap can involve numerous turns and braking actions, placing significant stress on the body. The physiological demands on drivers are comparable to those of athletes in other physically intensive sports.

While dietary intake data is available for athletes in many sports, there's a gap in understanding the nutritional needs of race car drivers. Adequate nutrition is essential for drivers to meet the demands of training and competition and to optimize their performance. This article explores a pilot study evaluating the dietary intake of long-distance race car drivers, comparing it against dietary recommendations for athletes and the general population, aiming to identify areas for improvement and optimization.

Dietary Intake and Performance

A 2018 pilot study assessed the mean energy and nutrient intake of long-distance race car drivers and compared it with recommendations for athletes and the general adult population in Germany. The study describes these drivers as athletes facing physically and mentally demanding sport and long hours of practice. A separate racing nutrition guide emphasizes maintaining hydration during a race, reporting that dehydration can quickly contribute to fatigue and reduced concentration.

Specialized Race-Day Nutrition

The supplied racing nutrition plan reports that drivers may burn 1,500 calories per race and argues for nutrition strategies tailored to cockpit conditions and cognitive demands. A race-day meal-plan source likewise characterizes motorsport nutrition as supporting endurance, focus, and resilience. The excerpts do not specify a shared meal protocol or quantify how much these strategies improve performance.

Sports Nutrition’s Shift to Science

A 2025 overview describes a broad change in sports nutrition: for centuries, athletes’ diets relied on tradition and guesswork, while modern practice draws on metabolic research. Professor Justin Roberts’s history of sports nutrition research traces how key discoveries shaped the field. The supplied sources do not identify particular discoveries or dates for milestones specific to race-car-driver nutrition.

Nutritional Pit Stops: Key Findings on Driver Diets

A recent study assessed the dietary intake of 16 male long-distance race car drivers preparing for a major 24-hour race. The drivers' diets were analyzed using 24-hour dietary recalls, and their intakes of energy, nutrients, water, and alcohol were recorded and compared to recommended levels.

The results revealed some concerning trends. On average, the drivers' intake of energy, vitamin B2, vitamin E, folate, fiber, calcium, water, and alcohol fell short of recommendations for both athletes and the general population. This suggests a widespread issue of under-consumption of vital nutrients among this group of athletes.

  • Energy Deficit: The majority of drivers failed to meet the recommended energy intake for athletes (3600 kcal) and the general population with a physical activity level of 1.8 (3000 kcal).
  • Carbohydrate Insufficiency: The mean carbohydrate intake was significantly lower than recommended levels for endurance and team sports.
  • Micronutrient Gaps: Many drivers had inadequate intakes of essential micronutrients like vitamin B2, vitamin E, folate and fiber, crucial for overall health and performance.

A Pilot Study and a Research Gap

The available overview identifies a gap in understanding race-car drivers’ nutritional needs, despite dietary intake data being available for athletes in many other sports. It describes a pilot study evaluating long-distance race-car drivers’ dietary intake and comparing it with recommendations. A separate 2026 racing nutrition article promotes carbohydrate requirements, race-day timing protocols, and hydration systems, but the supplied excerpt gives no specific values or study results.

Limits of Evidence and Individual Tolerance

The long-distance-driver pilot study lists its use of a single 24-hour dietary recall as a limitation. This means the study’s intake assessment rests on a limited time window, as the source excerpt notes. More broadly, endurance athletes need nutrition that supports fueling, performance during demanding conditions, and recovery, while exercise-related gastrointestinal symptoms can affect performance. The supplied sources therefore point to both measurement limitations and the importance of nutrition plans that athletes can tolerate.

While protein intake was within the recommended range for athletes, it's important to ensure adequate carbohydrate consumption to spare amino acids for protein synthesis and prevent their use for energy. Individual needs should be assessed based on age, height, weight, and specific training goals, ensuring drivers receive the right balance of nutrients to support their demanding physical activity.

Optimize Your Performance: A Personalized Nutrition Strategy for Race Car Drivers

The study highlights the need for a more focused approach to nutrition for long-distance race car drivers. Given the unique physical and mental demands of the sport, it's crucial to address the identified dietary gaps and optimize nutrient intake.

Nutrition for Health and Performance

The long-distance race-car-driver pilot study states that optimal dietary intake is essential for athletes’ health and performance. A separate case study on top endurance athletes focuses on how they plan meals, train nutrition, and fuel during competition. Together, the sources frame nutrition as part of athletes’ preparation and performance, though the supplied excerpts provide no individual athlete outcomes or specific meal plans.

Athletes should work with nutrition professionals to develop personalized dietary plans tailored to their individual needs, training volume, and competition intensity. This includes ensuring adequate energy intake, prioritizing carbohydrate consumption, and addressing any micronutrient deficiencies through a balanced diet or supplementation.

By prioritizing nutrition and addressing these key areas, race car drivers can fuel their bodies for peak performance, enhance recovery, and gain a competitive edge on the track. Further research with more long term dietary recalls is recommend.

What the recorded nutrient amounts show

  • 3.3 ± 1.5 g/kg/dayMean carbohydrate intake was 3.3 ± 1.5 g/kg/day, below the cited 4.0–6.8 g/kg range for endurance, team-sport, and strength athletes.[1]
  • 1.3 ± 0.7 g/kg/dayMean protein intake was 1.3 ± 0.7 g/kg/day: within athlete recommendations, but below levels reported for other sports.[1]
  • 2783 ± 1543 mL/dayMean water intake was 2783 ± 1543 mL/day, above the German general-adult recommendation of 2600 mL/day and higher than the amount reported for mountain runners.[1]

How to read the drivers' intake results

The contrast between carbohydrate and protein suggests that the dietary gaps were not uniform across nutrients: protein met the athlete benchmark, while carbohydrate did not meet the cited sports comparison range.[1]

Water intake exceeded a general-population benchmark, but that comparison does not establish whether intake matched drivers’ needs during competition.[1]

What the dietary assessment can and cannot capture

  • The authors noted that recording intake across three days could have assessed individual diets more accurately.[1]
  • Travel to the measurement venue may have changed eating patterns from the athletes’ usual environment.[2]
  • Comparisons with published research were difficult because the authors found no prior dietary-intake data for this driver group.[1]

How the drivers' diets were assessed

How the findings relate to other athlete data

The paper’s carbohydrate comparison spans endurance, team, and strength athletes; the drivers’ mean fell below the range reported for those groups.[2]

Protein presents a different comparison: it was within athlete recommendations, although lower than published figures for other sports.[2]

The study describes its contribution as the first published dietary-intake data for long-distance race car drivers, while noting that direct comparison with other work was difficult.[1]

Separate motorsport physiology studies report elevated demands during authentic racing and rally conditions; these findings describe the racing context, not a dietary comparison.[3] [4]

Questions the intake snapshot leaves open

  • Would intake recorded across several days give a different picture of individual drivers’ diets?[1]
