Designing a detailed map for an event.

I have been a mapping hobbyist for years and have recently begun trying to take it semi-pro. I'd like to be able to map out this race for you. I have a couple questions on the scope: Would this be a single map covering the high level route, start to finish, at the 333Km level? Or, would multiple maps be required for the different segments? Do you have the way-point coordinates available? - Mike
