Do you do 'running' run-ups?

In a seaplane, all the time g.

In my Mooney -- I see no reason to do so. By "run-up" I assume you mean
the portion of the pre-takeoff check list when the engine is at a faster
speed than idle.

How long does it take to run the engine up to 1900 rpm (or whatever it is
on your a/c), cycle the prop once (or however many times your POH -- not
your first instructor -- says to do it) and do a mag check? Fifteen
seconds tops? Rarely longer if something is found. And occasionally
longer if it's the first flight of the day.

Now then the parts of the pre-takeoff check list that do not require the
engine to be at other than idle, if there is a significant operational
advantage, I will sometimes do those on the roll. For example, check fuel
on fullest tank, seat belts, doors, windows, instruments, flaps, etc.
