After the update to software version 14.10 and after updating to 14.20 my treadmill runs have been throwing slower paces in the order of 12minutes /km when the machine is giving me just below 8 minutes/km, I have ended the treadmill activity about 2 or 3 times with the calibrate and save option entering the actual distance, but it seems there is no change, and the runs after calibrating keep the slow pace.
