Just because circular breathing isn't something you can do, that's no reason not to get this terrific chart. There are multiple ways to "simplify" its playing: slow the tempo; slur instead of double-tonguing; alternate phrases with a playing-partner; end on pre-arranged downbeats, grab a quick breath and keep going. If it's too high (lot's of high C's and D's), take those passages down an octave.
Search YouTube on "Moto Perpetuo Trumpet" for several virtuoso recordings.
My only "gripe" is with the PDF itself: the piano part (which has the trumpet part in small notes) and the separate trumpet part has a too-wide margin (a full inch); that results in the notes being smaller -- which is important for us older guys. Sharpness of the printed part however, is excellent.
