Use this tool to analyze an individual run. Download a .fit file from your watch’s app or desktop site, and upload to the tool. This tool will give you the following metrics:

  • Total Distance

  • Total Duration

  • Average Grade Adjusted Pace

  • Average Heart Rate Decoupling

  • Average Aerobic Efficiency

  • Average Grade Adjusted Pace at a selected aerobic heart rate

  • Average Grade Adjusted Pace at a selected threshold, or race-specific heart rate.

Measure distance on a known course like a track or measured course (with an accurate wheel).

Input current calibration factor, distance you actually ran, and distance Stryd thinks you ran to get new calibration.

Use this tool to analyze trends over a season. Feed this tool multiple .fit tiles of the same type of workout.

For example: Pick all easy long runs, or all tempo runs at a similar effort. Feeding it runs with similar routes and weather conditions yields a more reliable output.

This tool will track:

  • Run progress: Run distance, avg pace, avg HR

  • Easy Aerobic Efficiency: Pick a HR that fits your easy aerobic pace and track progress over time

  • Threshold Aerobic Efficiency: Pick a heart rate that’s more race-specific to your marathon, half marathon, or threshold pace. Then track progress over time

  • Heart Rate Decoupling Progress: Visualize heart rate decoupling trends over the course of the selected runs.
