Hi all
I use a forerunner 910xt to record my cycling activities. I have noticed on the last couple of group rides that i have been on that the distance has been inflated both on the watch during the activity, and on garmin connect once the data has uploaded. The max speed has also been inflated, for instance today i 'hit' 80+mph 9 times, clearly incorrect.
It appears that these inflated speeds has caused the inflated distances (but as im only speculating it could be the other way around - for example if the watch is 'jumping' gps points, then the increased perceived distance over the same time period could result in a spike in calculated speed).
Interestingly though when the same data is uploaded to Strava then it is interpreted correctly, the correct distance and no speed spikes. How can Strava interpret the data correctly and GC not? its the same data...
Here are links to the same activity on GC and Strava

when i am on solo rides there has been no errors. One thing i have noticed on both times when the distance/speed error has occured is that the 910 has asked me if id like to pair my power meter (i havent got one). Also I have noticed that the data shows a cadence speed (i havent got a cadence meter and it doesnt show a cadence speed on my solo cycling efforts). Dont know if these are significant but have included nontheless.
Can anyone help me get the correct data (most important for me is to have the correct data on the watch during the activity if im honest)
Thanks in advance folks
