Garmin Hill Score Alternative

Garmin Hill Score provides separate uphill and downhill running performance metrics based on your performance on graded terrain. It measures power output on inclines using grade-adjusted pace analysis, vertical oscillation data from the accelerometer, ground contact time balance, and barometric altitude changes. The feature rates your hill running ability relative to your flat performance, identifying whether hills are a strength or limiter. Scores update after runs with meaningful elevation change and consider factors like cadence changes on climbs, stride efficiency on descents, and heart rate response to grade.
