The metrics that fitness trackers don’t track
The Garmin epix Pro’s hill score measures running strength and endurance specifically during ascents and tracks progress over time, which is a metric that tells you something a heart rate zone or step count doesn’t: whether you’re actually getting stronger on elevation. The endurance score combines training data across all athletic pursuits to show how your cumulative training load is building or depleting overall endurance, which is the number that matters for anyone training across multiple sports simultaneously. Wrist-based running power gives real-time power output during runs without a chest strap or foot pod, and advanced pacing modes help calibrate race day output against training data rather than guesswork.
HRV status, Pulse Ox blood oxygen monitoring, and 24/7 health monitoring give a continuous picture of recovery and readiness that entry-level fitness trackers sample too infrequently to be meaningful. The morning report and training readiness feature synthesize overnight health data into a daily recommendation that accounts for sleep quality, HRV trend, and recent training load before you make any decisions about how hard to push in the day’s session. Advanced sleep monitoring covers sleep stages, respiration, and overnight HRV for the recovery picture that determines whether the training plan is working or accumulating fatigue.
