Garmin Connect / Forerunner 45 - Can I copy / paste an Activity to another day?

You could hack with exporting, editing, and reimporting the activity, but I would rather suggest creating a Workout, and then executing the workout. It will be then saved with the true data, and not with faked copied data from another day. I see no sense in having old data for new activities. That would completely eliminate the sense of having a fitness watch.

thanks, trux, much appreciated.

Is it too much trouble to ask follow up question?

I have also experimented with creating a Workout. I add it to my Calendar etc. but it only shows up as a Workout and is not reflected in Reports or Activities. Do I need to do "something" to activate it in Reports, Activities etc.?

Apologies for the noob question, but I am trying to get my round the most efficient way to record and track progress.

I think like the FR55, the 45 does not have native strength activities. You have to create them in disguise as a run or cycle activity, send it to your watch then when you've done the activity and it's uploaded you rename as Strength in GC  It's a bit of a faff but possible. I spent ages creating strength workouts in GC only to discover they can't be sent to the watch. A helpul forum member told me how to get around that. Once you hve created a workout you can add it to your calendar however many times you want, one by one though - there doesn't seem to be an ádd every Thursday' (or whatever) option. 

thank you again, trux, you are a superstar. After some investigation it turns out that the F45 does not support this function (for Strength training, at least).......
