Precision nutrition, not generic ranges.
FuelSense calculates exact caloric, carbohydrate, and hydration targets based on your specific ride — duration, intensity, temperature, altitude, and terrain.
Your ride burns different every time.
A 4-hour ride at 18°C burns differently than a 4-hour ride at 32°C with 2,000m of climbing. Generic nutrition guides can't account for this. FuelSense can.

Caloric Expenditure Modeling
Precise energy expenditure prediction that factors in gradient, wind resistance, temperature, altitude, and rider weight. Not a simple watts-to-calories conversion — a multi-variable physiological model.
Energy expenditure by segment
Carbohydrate Pacing
Gram-per-hour carbohydrate targets that adapt throughout the ride. Higher intake before climbs, lower during descents, and progressive increases as glycogen depletes over time.
Carb target g/hr by ride hour
Progressive loading · higher before climbs
Hydration Intelligence
Fluid loss modeling that accounts for temperature, humidity, altitude, and effort intensity. Not "drink 500ml per hour" — drink 650ml at km 72 because the temperature is 28°C and you're at threshold.
Fluid rate vs. temperature
Per hour · at threshold intensity
Fueling Window Placement
Every gel, bar, and bottle is placed on your route timeline at the optimal moment — before you need it, not after you notice it. Pre-climb loading. Post-effort replenishment. Caffeine timing.

Bonk Risk Prediction
Route-ahead glycogen depletion modeling that flags when your fueling plan puts you in the danger zone. If your targets slip behind schedule, FuelSense adjusts the protocol to prevent catastrophic energy failure.
Glycogen depletion forecast
Temperature-Adjusted Targets
Heat increases fluid loss by 20-40%. Cold suppresses thirst signals. FuelSense adjusts every target based on the actual temperature at each point on your route — not the forecast for your city.
