Hello @WalkerRon 

Thanks for posting about this and sorry to hear that happened.   It's likely that you had a weak GPS signal for this recording.  When the GPS signal is weak, less data is recorded and it's common for distance to be overestimated.  

A number of things can cause poor quality GPS data.  Check out this link for information on troubleshooting GPS issues

Let me know if that helps and if you continue to have issues with future recordings.
