HealthKit Run Generator
A Swift Package for generating realistic HealthKit running workout data — outdoor runs with GPS routes and indoor treadmill runs with accurate physiological metrics. Built for developers who need real-looking test data without going for a run.
Outdoor & Indoor Runs GPS routes with elevation, treadmill simulation with incline profiles
Physiological Accuracy Heart rate curves, cadence, pace splits — all following real exercise physiology
5 Run Profiles Easy, tempo, interval, long run, and race — each with calibrated metrics
Deterministic Seeds Reproducible output for snapshot testing and CI pipelines
Training Plans 4-week periodized cycles with progressive overload and recovery weeks
Batch Generation Generate hundreds of runs with seed ranges and JSON export
