Constant tail wind in ride files

Hey John,
for my past couple of rides with my PowerPod there seems to be a 13 to 15 km/h tail wind all the time.

I calibrated the PowerPod with an out-and-back ride. As far as I can tell the profile looks OK (not too far off from the generated profile during the initial calibration ride). The setup of my bike did not change either.

I attach one of my ride files.

Any idea what is going wrong?

Thank you,

Guido

A consistent tail wind indicates an incorrect wind calibration from the out and back ride.

I'd like to see the cal ride that preceded the ride file you posted. The ride file you posted has a wind factor of 1.600---almost an impossibility for an O&B ride.

Did you do any drafting in this ride?

Hey John,
sorry for the long time not replying.

Please find the ride file of my out-and-back ride attached. It is a 16km ride. Since I am living on a hill I cut it out and used the section from 1.8km to 14.1km for the calibration.

Regarding the ride file I posted earlier (06_25), there should be no drafting in there. But I am not entirely certain.

Thank you for your help,

Guido

The 5/14 ride looks fine.
