Overview

FitGlue activities uploaded here benefit from Intervals.icu's advanced charting, fitness/fatigue tracking, and power analysis.

How It Works

Activities are uploaded with available metrics and booster descriptions. Intervals.icu processes the data and integrates it into your training calendar.

Configuration

Common Issues

Duplicate activities — If Intervals.icu already receives the same activity from another source (e.g., Garmin Connect), you may see duplicates. Disable the duplicate source or use only FitGlue as the input to Intervals.icu.
