You'd probably have the M-P's named after the circuit name
(Watkins-Glenn) & the ways after what class of race they're used for
(Grand Prix Circuit, Nascar Circuit etc).
Note that highway=raceway renders as a thick line in Mapnik so the track
will appear wider than it actually is, but remember we're not tagging
for the renderer.
An alternative might be to tag as this horse race course (substituting
the obvious, of course)

No, not for the renderer, they only render what is tagged, not what is
There is an argument for putting it into rivers though, to indicate what
size of craft can navigate. Care has to taken to ensure that the way
goes as near to the centre of the river to ensure the width doesn't
bleed over the riverbank.
Post a link when you've completed it; I'd like to see the results.
