ClipZip Stopwatch

I chose the ClipZip over an Apple product because it has the stopwatch and log feature.  I would like to use the ClipZip to log my daily jogs.   These are single events with no laps, ie. start then stop.  It seems without recording at least one lap, the time is not saved in the log.   What I would like to do is start - stop - save to the log, but don’t seem to be able to make it do that.  Am I missing something?   Thanks.  /John
