About

Born from Experience

Ultra Nutrition Calculator was created by ultra runners, for ultra runners. After too many races ending in nutritional disaster—bonking at mile 62, dealing with severe GI distress, or hitting the wall when victory was within reach—we realized there had to be a better way.

The problem wasn’t a lack of effort or training. It was nutrition planning. Or rather, the lack of accessible, science-based tools to create proper nutrition strategies.

The Traditional Approach

Most ultra runners plan their race nutrition using:

• Generic “60g of carbs per hour” rules
• Trial and error during training runs
• Copying what worked for someone else
• Gut feelings (pun intended)
• Advice from the last blog post they read

This approach works… until it doesn’t. And when it fails at mile 75 of a 100-miler, there’s no second chance.

A Better Solution

We combined peer-reviewed sports nutrition research with real-world ultra running experience to create a calculator that:

• Accounts for individual differences (weight, pace, conditions)
• Provides personalized recommendations
• Considers scientific principles of absorption and timing
• Makes complex calculations simple and accessible
• Helps athletes test and refine their strategies

Evidence-Based Nutrition. We base all recommendations on peer-reviewed research from:

• International Society of Sports Nutrition (ISSN)
• American College of Sports Medicine (ACSM)
• Studies on ultra-endurance events
• Validated sports nutrition guidelines

Real-World Testing Theory meets practice. Our formulas have been:

• Tested in races from 50K to 100+ miles
• Refined based on athlete feedback
• Validated across diverse conditions and terrains
• Used successfully by runners at all levels

Personalization Matters

No One-Size-Fits-All. Your nutrition needs depend on:

• Your body weight and composition
• Race distance and duration
• Effort level and pace
• Weather conditions
• Altitude and terrain
• Individual tolerance and preferences

Your Strategy, Your Way. We provide the framework, you make it yours:

• Customize to your preferred fuel sources
• Adjust based on your experience
• Test and refine in training
• Save multiple strategies for different scenarios

Accessibility is Key

The Beginning

Founded by a group of ultra runners who were tired of DNFing due to nutrition failures, Ultra Nutrition Calculator started as a simple spreadsheet shared among friends.

The Catalyst After a particularly brutal race where three of our team members dropped due to nutrition issues—despite months of training being perfect—we decided something had to change. We spent the next six months researching, calculating, and testing.
