First outdoor ride. Need assistance!

[romi]

Hi!
This is the first outdoor ride. Until today I used PP only on hometrainer or roller.

Could you please take a look to my ride to see if is OK? It was O&B calibrated with few days ago.
The 108km ride had a coffee break almost at the middle so PP recorded two rides. What I do not understand is why the cumulated rides have only 78km. One is 44km and the other is only 34km. There are 30km missing. Nevertheless, the PP send to Garmin (see ride file) the power data for all 108km...

One mention. On hometrainer or roller ,the Garmin unit showed me all the time the power data sent by the PP so there was no zeroes. On the road, Garmin showed frequently zeroes even if my cadence was continuous. Was the ANT+ transmission between PP and Garmin affected by passing near high voltage line, powerplants or any other radio signal generators or static electricity?

Thanks a lot for further help!

A little help?

It looks like you are using a magnet less speed sensor.

Place the speed sensor on your front hub. That will get rid of the speed dropouts, which are why distances traveled are different.

Otherwise, the file looks fine!

It is not a magnet less sensor. It's a combo sensor mounted on the left chainstay.
The same sensor was used (in the same position) for indoor training and I did not noticed so many dropouts.

Those dropouts could be a matter of radio waves interference?
