Eat for the
session ahead. Not the one behind.

FuelSport reads your TrainingPeaks plan and generates a precise nutrition plan for the day — before you even think about food.

How it works

From training plan
to dinner plate.

FuelSport reads your TrainingPeaks calendar and works backwards — calculating everything you need to eat before you even think about it.

01
TrainingPeaks reads
Every night at 22:00 we pull your planned workout — TSS, IF, duration, type, start time.
02
Engine calculates
Our nutrition engine models your glycogen deficit and calculates CHO/PRO/fat targets for each meal of the day.
03
You get the plan
Push notification with your dinner plan tonight, breakfast time, in-route fueling, and recovery window.
04
TP gets updated
The nutrition plan is written back to your TrainingPeaks calendar. Your coach sees everything in one place.
Features

Built for athletes
who train seriously.

🔋
Glycogen model
Real-time estimation of muscle and liver glycogen based on TSS accumulation, carb intake, and fasting hours. Coach can override with lab measurements.
Core engine
📸
Photo validation
Photograph your meal — AI detects ingredients and macros, then compares against your daily plan. "Does this work for tomorrow's sprint?" answered in seconds.
AI powered
⚡
Recovery window
When your TP workout transitions to completed, FuelSport triggers an instant push notification for the optimal post-session nutrition window with a live countdown.
Real-time
🏋️
Multi-sport model
Cycling uses power/kJ. Running uses pace + HR. Strength uses MET + EPOC. Double sessions handled with gap analysis — nutrition adapts to the actual demand.
Science-based
🧠
Adaptive learning
Post-session RPE and energy feedback trains the app on what works for you. After 30 sessions, a personal regression model predicts your optimal nutrition with increasing accuracy.
ML · Level 2
👨‍💼
Coach panel
Coaches see their athletes' glycogen status, recovery score, and nutrition compliance alongside training load. Input lab glycogen measurements to calibrate the model.

We complement TP.
We don't replace it.

FuelSport is a nutritional intelligence layer on top of TrainingPeaks. Athletes keep their existing training workflow. Coaches keep managing plans in TP. FuelSport adds the one thing missing: a nutrition plan that automatically follows the training plan.

The bidirectional integration is key — we read the training plan, generate the nutrition plan, and write it back. The coach sees everything in one place without leaving TrainingPeaks.

🔗 We are requesting Partner API access to begin sandbox integration. Our nutrition engine is production-ready and validated against real athlete data from cyclists in Chile.
