Hmm... I might look at doing something similar for Biking Across
Kansas. Not sure if these event routes really belong in OSM as a route
relation though. They do not indicate a route that should be generally
preferred for bicycles. It is just specific to a single event and only
to event participants. So this seems like a case of tagging for the
renderer.
