Connect recorded the complete Enduro GPS route accurately during a 1 hour and 32 min hike. Plotting the recorded data with time results in an accurate plot. Plotting the recorded data with distance results in a bad plot. (Incomplete.). Somehow the distance data became corrupt. The response I received from Garmin Support was that it was likely a one off since this error has never happened to me before. Somehow the file became corrupt. Support suggested that I delete this activity from my Garmin Enduro directly.
