I finished a hike today, hit the stop button on my 305 but didn't turn the unit off. Then I drove home.
This of course left me with TWO laps (the hike and the ride home). When I noticed this in TC, I went back to the 305 and deleted the 2nd lap.
Then I uploaded the hike to GC. On the Splits tab, GC shows only the one lap. BUT on the Google map, I see BOTH laps!
It appears that GC is reading and incorporating the deleted lap info into Google maps. That is a BUG!
