I would like to temporarily trim the beginning of a bike ride. Once I trim, let's say the first 10 minutes is that data lost forever? I'm interested in trimming these slower portions of my ride in order to get a better idea of my average speed once I've warmed up (but I still want to begin the activity from my home). Once I've determined and seen the data I want can I recover from the trimming of data and restore to original?
