Fuel Your Ultra with Science

Research-proven nutrition packs designed for ultramarathon runners who refuse to DNF due to poor fueling

Why Runners DNF: The Nutrition Crisis

Ultra events lasting beyond 24 hours demand between 13,000-17,750 kcal, yet most runners only consume 36-53% of required energy. This massive deficit doesn't just slow you down—it destroys performance, compromises recovery, weakens immune function, and dramatically increases injury risk.

Most ultra runners consume only 37g of carbohydrates per hour—less than half the recommended 60-90g/h minimum. Research shows runners consuming under 200 calories per hour are significantly more likely to DNF, while finishers consistently consume over 250 kcal/h.

The Science Behind Performance

What Elite Runners Know

Research published in leading sports nutrition journals reveals the performance edge that separates finishers from DNFs:
90-120g/h
Optimal carbohydrate intake for elite ultra runners
2:1
Glucose to fructose ratio maximizes absorption via multiple transporters
500-700mg/L
Sodium concentration needed (most products fall short)

Multiple Transportable Carbohydrates: Using glucose and fructose together enables absorption rates up to 120g/h, surpassing the 60g/h limit of glucose alone. Studies show 120g/h intake significantly reduces exercise-induced muscle damage compared to 60-90g/h.

Gut Training Works: Athletes who practice high carbohydrate intake during training develop enhanced intestinal absorption capacity and reduced GI distress. Research demonstrates that trained athletes tolerate significantly higher carbohydrate loads.

Electrolyte Balance is Critical: Fluid volumes of 450-750 mL/h with sodium concentrations exceeding 575 mg/L minimize hyponatremia risk. Both dehydration (>2% body weight loss) and overhydration can devastate performance.

Pre-Race Loading Matters: Carbohydrate loading at 8-10 g/kg body weight for 48 hours pre-race correlates directly with improved race distance and completion rates. Higher pre-race CHO intake shows positive association with ultra-running experience.

Low-FODMAP Strategy: For runners with GI sensitivity, implementing low-FODMAP diets during key training periods significantly reduces gastrointestinal distress during racing.

Performance Benefits You'll Experience

↑ 20%
Improved race completion rates with proper fueling
↓ 60%
Reduction in GI distress symptoms
Faster
Recovery and reduced muscle damage markers

Sustained Energy Output: Maintain optimal pace longer before fatigue by preventing glycogen depletion and maintaining blood glucose levels

Enhanced Neuromuscular Function: Higher carbohydrate intake (120g/h) limits neuromuscular fatigue and preserves high-intensity run capacity even after extreme distance events

Reduced Muscle Damage: Research shows significantly lower markers of exercise-induced muscle damage (CK, LDH, GOT) with optimized carbohydrate protocols

Faster Recovery: Adequate intra-race nutrition accelerates post-exercise recovery, allowing quicker return to training or multi-stage events

Mental Clarity: Stable blood glucose prevents the cognitive decline that leads to poor decision-making in late race stages

Immune Protection: Meeting caloric demands during training prevents the immune dysfunction associated with chronic energy deficit
