i often forget to stop my watch immediately upon completing and activity. Sometimes I have to stop for a train crossing, or to wait my turn at a trail obstacle.I would like a tool to easily declare on the map in Garmin Connect where or when the activity ended, or make a few minutes to be deleted, and have it remove any of those data and recalculate all of the statistics.
I have several friends who have this issue, and I'll be very surprised if this isn't a common lament. I check these out - http://www.dcrainmaker.com/tools - but they seem kinda complex for my limited skills and patience.
I don't see the menu choice Trim Activity. Is it still there for you
Yes, it is still there, though not for every activity type. As written in my previous post, if you need to trim an Activity of a type that does not offer the trimming, change its type temporaily to Running, trim, and then set the type back to the original one.
