Time to dust down the viola for a bit of Bach.
I also have the Cello Suites for horn, for which an aqualung is advised and you have to do fancy glissandi to catch all the notes of the quadruple stops, but they are still pretty playable.
A fave from Suite 2
You will be staggered I am sure to know that I don't play it that fast, mostly, even if it is a courante. I never could run that fast.
