AeroPod, PowerPod and Newton

John,
is it possible?

as you said is very difficult to judge the winds on the bike.... but i felt both headwind and tailwinds very notorious.

Here is the ride file where the wind is always headwind.

thank you

This ride file shows an overall headwind, despite the fact you're riding on a closed circuit.

I used the Check Calibration feature to correct this.

Corrected ride file and profile are attached.
