b/w OP, whatever you do, DO NOT HURRY and try to get out someones way. hurrying during run up (or anything in aviation for that matter) doesnt end well.
As a student pilot, the runup definitely takes a little longer, and you don't want to hold up traffic. So I understand the OP's concern for a specific run up area.
That's basically my objective: To find a place where I can do the runup without blocking anyone and not feeling the pressure to hurry up because there are people waiting.
