Garmin Running Smartwatches

Training Readiness is a daily score (typically 1 to 100) that tells you how prepared your body is for a strenuous workout right now.

VO2 Max is the maximum rate at which your body can consume oxygen during maximal exercise. On a Garmin running watch, it is calculated automatically during outdoor runs (or indoor runs/bikes with a power meter) by analyzing the relationship between your pace/power and your heart rate.

The Morning Report is a customizable summary that appears on your watch screen when you wake up. Importance of wearing it overnight: The most crucial data for these metrics—especially HRV Status and Training Readiness—is collected during sleep. This is when your body is at rest, allowing the watch to establish a reliable baseline of your autonomic nervous system function, which is critical for accurate recovery and readiness calculations.

Acute Training Load is a measure of the total exercise stress your body has incurred over the last ∼7−10 days, with recent workouts having the most weight. It's essentially a rolling seven-day average of your workout intensity (measured as EPOC).

Running Dynamics are advanced biomechanical metrics that analyze your running form and efficiency. They are essential for runners looking to fine-tune their stride and reduce injury risk.
