One test.
30+ metrics. Zero guesswork.
Your athlete runs one test — you get VO2max, training zones, fuel curves, and race-day targets. All from peer-reviewed sports science.
Built for endurance coaches
Replace your spreadsheets and calculator hacks with a platform that does the sports science for you.

From one test to the full picture
Three efforts, 30+ metrics. From VO2max and lactate thresholds to training zones, fuel curves, and glycogen estimates.
Test results
Performance trends
Fuel curves
Race strategy starts with the course
Upload a GPX file and Raceday breaks it down — climbs, gradients, elevation profile — so you can plan power targets and nutrition for every segment.
Full course breakdown
See where the hard parts are — every climb, descent, and flat stretch visualized on an interactive map.
Automatic climb detection
Raceday finds every climb automatically — distance, elevation gain, and average gradient for each one.
Segment-by-segment targets
Set power targets, cadence, and nutrition for each segment based on your athlete's test data.
Plan every detail
Build complete race strategies with climb-specific power targets, pacing strategy, and a nutrition schedule down to the minute.
- ✓Climb-by-climb power targets
- ✓Timed nutrition with repeating intervals
- ✓Auto-suggested targets from test data
- ✓Full triathlon support (swim/bike/run)
- ✓PDF exports and shareable report links
Built on real sports science
Every calculation is grounded in established sports science models — not generic formulas.
Mader model
Lactate dynamics and VLAmax from the gold standard in metabolic modeling.
Cooper test
VO2max estimation validated across thousands of athletes since 1968.
7-zone model
Training zones derived from individual anaerobic threshold, not generic HR percentages.
