Hi,
I've bought my Edge 1040 7 days ago (22th of July).
I made some 3km slow test ride after mounting it.
Dont know why and how I got FTP result from this ride
while not having any power meter. I used only Garmin HRM-Pro.
See garmin connect screenshot below.
It says: "FTP ratio from bike ride 263W 22th of July"
Is it possible to make another FTP test? and how?
