Rafal Nazarewicz, Spring co-founder with a PhD, discusses the use of real foods in ultras. Topics include runner's gut variability, hydration, a unique rice and fruit-based product, coconut oil controversies, energy shifts in ultra races, electrolyte composition, sodium loss balance, innovative energy gels, and the shift towards whole food fueling for endurance racing.
Gut health is crucial for endurance performance, focus on maintaining rather than just food choices.
Hydration is vital for gut function during races, opt for high osmolarity foods and specialized drinks.
Real food-based products like micro-meals may aid in addressing GI issues and sustaining energy levels.

The Impact of Race Day Nutrition on Gastrointestinal Discomfort
Long-distance runners are more likely to experience gastrointestinal discomfort during races. Factors such as heat and altitude can influence appetite and symptoms. While choosing suitable foods is essential, the integrity of the gastrointestinal tract, including cell viability and microbial communities, plays a crucial role in prolonged races.
Muscle Trauma and Gastrointestinal Health during Races
Similar to how muscles experience trauma during running, the gastrointestinal tract also undergoes strain during ultramarathons. The function and integrity of the gastrointestinal tract are key factors in sustaining endurance performance. Understanding and maintaining gut health is more critical than solely focusing on food choices for optimal race performance.
Considerations for Maintaining Gut Strength
The constant renewal of intestinal cells every five days and the dynamic nature of gut microbial communities highlight the adaptability of the gut. The importance lies in keeping the gastrointestinal tract robust and functional, rather than solely focusing on identifying ideal food options for endurance events.
Hydration and Osmolarity in Gut Health
Staying hydrated is crucial to maintaining blood volume and gut blood flow during races. Foods with high osmolarity, like complex carbohydrates, are preferred over simple sugars as they promote gut health. Specialized drinks like Enterade, containing specific amino acids, can aid in maintaining and restoring gut strength and viability.
Innovations in Nutrition Products and Their Impact on Athletes
The development of real food-based nutrition products like micro-meals aims to offer balanced and convenient nutrition options for endurance athletes. These products, incorporating elements like slow-release carbohydrates and fats, show promise in addressing gastrointestinal issues and sustaining energy levels, leading to improved race performance.
