Before that: The entire Piano Concerto in Eb Major (Emperor) by Beethoven. (It took me a long time to enter the room, obviously... And I was rather Imperious. ::dry chuckle::)

Now: I would choose 'Post of Honour' which is the second piece in a trilogy I wrote/am still trying to complete (Grr!) for brass quintet. Or maybe 'The Green Gauntlet' which is the third piece. (The first piece, 'Long Summer's Day', is too slow for walking.) It would depend on the situation.
