Activity editing?

Hi guru’s,

I’ve a Garmin Fenix which I use amongst other things for sailing (racing dinghies).  In bad weather, the watch is underneath my drysuit sleeve and so inaccessible whilst I’m zipped up and on the water.  I start the activity recording before and end it once I’m unzipping to change.  There can be as many as 3 races in this time which the activity records happily.  Post activity, I’d like to split the 3 events but I can only find how to trim the whole activity and not how to split it.

When I trim, I lose that segment which I’ve not kept.  Can anyone advise me how I can achieve my goal and split the recording and data into 3 events please.

cheers!
