Aha, this is just the situation that calls for a "rolling runup."  Do it on
the (long) taxiway toward the takeoff runway.  Everything is the same,
except you use the brakes to keep at normal taxi speed, rather than use the
brakes to stay stationary.  Yes, it does wear the brakes a bit, but not more
than a short field landing will.

A very useful trick that my CFI taught me many years ago, and I've found
several occasions (at big-iron airports) where it really saves time and
confusion.

At an unfamiliar towered airport, you can also ask GND if there is a runup
area at/near the threshold hold point.  If not, then do it on the roll.
