Two weeks to go; Brick question

First tri, a mini sprint (400yds/8mi/1.8mi), is two weeks away.  This week, I’m going to add a few brick workouts as I get closer to the first race.   It’s about two miles to my local swimming pool.  I was thinking about riding the bike over, swimming a few hundred yards then biking home.  Hell, I could even hop off the bike and run some after getting back home.  After a very rough start with the swim and some rudimentary reacquainting with the bike, I feel like none of the distances are particularly challenging now (he says waiting for the lightning to strike him).  When putting together the brick workouts for the next week, should I be focusing more on distance or process?  I did one swim to run without about 10 minutes in between--not a real indicator.  Is it more about acclimating your body to shifting from discipline to discipline quickly or does the distance preceding the shift make a real impact?

 Thanks in advance for the sage counsel I always get here.  I appreciate it more than you know.
