AI-Enhanced Training Calculators
Seven smart calculators that go beyond static formulas. Enter your data and get adaptive, phase-aware results tailored to your training.
AI TDEE & Macro Planner
Get a personalized weekly nutrition plan that adapts macros to your training schedule, phase, and goals — not just a single daily number.
Open Calculator →AI Training Zones Calculator
Generate zones across all three disciplines simultaneously, with real-time fatigue adjustment. Static calculators do one sport at a time — this does all three at once.
Open Calculator →AI Race Performance Predictor
Enter up to 3 past race results and your training details. The predictor blends multiple data points with recency and distance weighting — far more accurate than a single-race Riegel formula.
Open Calculator →AI FTP & VDOT Estimator
Combine your cycling test data with race results for a confidence-weighted fitness estimate. See your W/kg category and running VDOT side by side.
Open Calculator →AI Recovery & Readiness Score
Enter your morning metrics and get a go/no-go recommendation for today's training. This composite score weighs multiple factors — something no single metric can do alone.
Open Calculator →AI Training Load Optimizer
Set your current fitness, target CTL, and race date. The optimizer projects day-by-day training stress with automatic taper scheduling and injury risk warnings.
Open Calculator →Macro Periodization Engine
This is not a daily macro calculator — it's a full mesocycle planner. See how your nutrition should shift across weeks of training, with carb cycling by day type and progressive adjustments.
Open Calculator →Training Guides
Go deeper with our free training methodology guides — race pacing, equipment strategy, and more.
