I use a Garmin Fenix including the external heart rate sensor.
After a run - the time until the heart rate is back to normal is shown.
This is - following the lates studies - one of the most important factors to be known.
It would be great to access the data afterwards (in addion HR after run - HR at rest - time to cool down)
Much better would be to get this in form of a chart to be visible.
Maybe others have the same need ??

Bernd
