Each tool contains multiple calculators — pick a category to explore them all.
Nutrition Intelligence Hub
Fueling is personal. Use our interactive tools to calculate your specific needs for carbohydrates, hydration, and daily nutrition.
Session Details
Tip: High intensity refers to sessions near or above threshold (Zone 4/5). Low intensity refers to easy recovery efforts (Zone 1/2).
Recommended Intake
"Small amounts of carbs can help performance. A mouth rinse or small sip is often enough."
Practical Equivalents (per hour)
Conditions
Estimated Total Loss
Sodium
Critical for fluid retention
Potassium
Supports muscle function
Recommendation
Standard hydration strategy. 1 electrolyte serving is likely sufficient.

Growth Intelligence Hub
Use our interactive tools to calculate your optimal protein intake, calorie surplus, and genetic muscle-building potential.
Research: 1.6-2.2g/kg/day maximises muscle protein synthesis. Higher intakes show no additional benefit for most individuals.
Berkhan Formula: Max lean body mass at ~5-6% body fat = Height (cm) - 100. This provides a realistic ceiling for natural lifters.
Power Intelligence Hub
Use our interactive tools to optimise your training load, power output, and stimulant timing.
Epley Formula: 1RM = Weight × (1 + Reps ÷ 30). Most accurate for rep ranges of 2-10.
Half-life: Caffeine has a ~5hr half-life. After 5 hours, half the dose remains active in your bloodstream.
Health Intelligence Hub
Optimize your daily protocol with our specialized health calculators.
Select the time you need to be awake and alert.
The Science: Sleep occurs in 90-minute cycles. Waking up at the end of a cycle leaves you feeling refreshed. Waking up in the middle of deep sleep causes grogginess (sleep inertia).
Includes 15 mins to fall asleep.
approx 13 glasses
Tip: This includes water from all sources (coffee, tea, food). Aim to drink consistently throughout the day rather than all at once.
Endurance Intelligence Hub
Use our interactive tools to dial in your race nutrition, pacing, and hydration strategy.
Science: Endurance events >90min require 60-90g carbs/hr. Dual-source carbs (glucose + fructose) allow absorption rates up to 90g/hr.
Negative splits (faster second half) are the hallmark of a well-paced race.
Recovery Intelligence Hub
Use our interactive tools to calculate your recovery needs, sleep debt, and optimal supplementation timing.
Research: Sleep debt is cumulative. Even 30 minutes of lost sleep per night compounds into significant cognitive and physical impairment over a week.
Research: Recovery readiness combines sleep quality, muscular recovery, stress load, and autonomic nervous system markers. Higher scores indicate greater training readiness.
Research: Timing recovery supplements relative to your training and sleep schedule maximises their effectiveness. Magnesium and glycine work best 60 minutes before bed.
