Not 100% sure since I wasn't able to ride it last year. I looked over the cue sheet though and it's basically a lot of the same roads I ride anyway. Through the city has got to be a pain though - you end up going through manayunk, down into the city through the usual bike paths (kelly drive), and then down to the Naval yard in south philly... I'm sure the areas up in montgomery county are a little nicer with less traffic.
