I accidentally rideing in indoor bike mode and there is no GPS data.
Is it possible to create GPS data as if it were running outdoors?
How do you synchronize geometry and GPS?
What kind of app do you use to create GPS?
perhaps this will get you started
explain how you did it or is it too complicated?There were several steps, but briefly:
- Using Garmin Basecamp I created a new GPX file that includes the missing portion, which I created from the original, just inverted it.
- Using Fit File Repair Tool with your imported original Fit file, used the "Add position data from GPX file" feature to create a new fit file with the corrected GPX information.
Your issue is not a common occurrence. Rather than trying to repair all your past activities, I'd suggest making sure you have a GPS lock before starting an activity. That's usually why the start of an activity will be missing GPS data.
