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.

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.
