I have recently switched to Garmin and I am having issues with the watch dropping out / switching off during a run. This has happened about 4 times now in the last 10 runs (it also happened on the very first run but I assumed I had somehow stopped it). It has typically stopped recording in the early part of the run. I have both the GPS + GLONASS activated which is supposed to assist with acquiring satellites. These runs are not in heavily built up areas &/or with dense tree coverage so this should not be a problem. The watch is fully charged, is on the latest update 9.20, Auto Pause function is OFF, and the Data Recording is set to Every Second. I have not been able to find anything on this forum relating to this issue. I have also spoken to other runners at the club who use Garmin and they have not experienced this issue.
same issue here. Experienced 3 times in last two weeks. Initially I thought the unit was not charged enough but next time I paid more attention. When it went dark after about 50 minutes into the workout session I switched it on again and it recorded another 1-K and it went dark again. I switched it on 3rd time and recorded the rest of session. When I saved the session battery was still at 60%!
So I thoguht it's perhaps because using custom Data Field and switching between screens in interval workout mode but yeasterday it happend in easy 10-K run w/o any fiddling with the watch. In contrast it worked just fine on Sunday for 2h+ long run. The only difference is I was using pace alert in the last easy run and not in the long run.
I've been using the 735xt unit for about 10 months (3-4 months of structured running using interval and tempo workouts) and there were no problems before but only now. The unit was on version 9.10 when it happend first 2 times and 9.20 yesterday.
