A quick search shows a lot of people asking about this, but it seems Garmin thinks this is unnecessary and has not bothered to implement.
Or perhaps it's too difficult to add this feature?
A 2km hike I did over 34 minutes up and down different terrain plays in 18 seconds, and I would like to have the option of slowing it down 2x to 8x or higher, and replaying in real time would be fantastic for watching cadence, heart rate etc.
I know you can manually move the sliders at whatever speed you want, but that's just not the same.
