Sessions
How your sessions get in
-
Drop a .fit, .gpx or .tcx here
Or choose a file. It never leaves this tab.
-
10 real minutes on Lake Garda, already analysed.
-
Paste your intervals.icu key in Settings. Sessions arrive by themselves. Garmin Connect’s phone app cannot export a file.
-
Take this one on the iPhone app. A browser cannot reach your watch.
-
Take this one on the iPhone app. Apple Health is closed to a browser.
-
Export the file. Then drop it here.
-
Take this one on the iPhone app. Strava sign-in needs it.
What you get
.fit, .gpx and .tcx all work. What each one
can show differs.
Free, no account. Your file never leaves this browser tab. The analysis runs on your own device.
- Starting the analyzer
- Loading the analysis engine
- Reading the FIT file
- Analysing
The engine downloads once, about 14 MB, then stays in this browser. The next file starts straight away.
A long session recorded with the accelerometer can take several minutes. The tab is working, not stuck.
That file could not be analyzed
Most often the file is not a FIT recording. Or it is a converted export rather than the original file from the watch. On intervals.icu or Garmin Connect, choose Download original file.
If the message below counts recordings, the .zip
holds more than one. Unzip it and drop the single session you want.
