I've had a ton of Garmin watches over the last decade, and can't remember the last one that wouldn't let you rename activities. She wants a "Hike" activity, and "Tennis" activity; neither exist, and I can't find a way to copy over an existing activity and rename it to one of those two. She's irritated enough with this (seriously, this should be a fundamentally easy thing to do on this watch) that she wants to return the watch if she can't do it. So, someone please help before she ditches it... thanks!
