I have been using my FR920XT for a few years now but have not been right into my running as I have been this year. I am down nearly 11kgs since the first week of January and running consistently four times a week. Currently training for a half marathon. My first ever, and yet to be fully planned due to Covid-19 and all races cancelled. Hoping for July 2020.
That aside, I am finding that the FR920XT is not as reliable as I'd like it. It is all up to date and I have tried to contact Garmin via email about it. It sometimes will not sync data across at all. Sometimes, just to Garmin Connect but then not Strava. So because of this, I have been running with the FR920XT on and also recording on Strava on my iPhone 8+ so I do not miss any data.
What I am also now noticing is that the GPS data is a lot less on the watch vs the iPhone. I did an 11km run on Sunday. iPhone in Strava was 11.04km, but my FR920XT was only 10.46km. The gap is progressing as I run further.
Has anyone else experienced big differences in GPS distance between devices? It's quite frustrating. If it was only 10/20 metres I wouldn't worry, but nearly half a km over 11km is not good.
