Hi guys,
I have contacted Garmin with this issue, but perhaps someone here can help.
I did a ride yesterday. Basically a ride to a coffee shop and back ride along a towpath with daughter in a trailer :)
When I got the the coffee shop I stopped the clock and hit the lap button and started again on the way back.
When I got home and synced to Garmin Connect the first half of the ride is missing off the graphs and map, but is included with the average speed, distance etc.
If i look at the data in Training Center all the data is there.
Here is the activity link.

I have attached screen shots showing the issue.
I looked back on my history and its the same issue with some of my other rides.
Many Thanks
Alan
