> I'm not using intervals :-)
Ah ok, sorry, a little misunderstanding :-)

> Could this issue be caused by assisted GPS not working due to lost phone signal and/or internet connection?
Could be, but should not happen. The GPS should work also without assisted GPS for a while.

I've found a related discussion:

https://code.google.com/p/android/issues/detail?id=81140

and also some suggestions on how to solve the problem.

General ideas to improve GPS reception:
- Not use Bluetooth (Android Wear) (as a test)
- Place the device in a different spot

I'm not using intervals :-)
I used the word 'interval' to point out that the issue occurs with a frequency/interval of 20 minutes.
Could this issue be caused by assisted GPS not working due to lost phone signal and/or internet connection?

Hmm I don't think it has to do with the smart watch: no special data is sent to the smart watch when the interval is switched.

Does this always happen when you use intervals? If so, I'll dive a bit deeper into the issue and try to reproduce it.

No BT headset was used during these trainings; a wear watch was used!

Though an Android wear watch was used (LG G watch R)!

Very strange indeed.

Could it be because the spoken announcements when a new interval is started somehow influences GPS reception? Are you using a Bluetooth headset?

Strange that the 'GPS signal lost' warning sounds every 20 minutes (interval is precisely 20 min)!?
See for example these training sessions, GPS signal spikes each 20 minutes:
