Not sure if anyone will find this useful, but I made a little MS Paint version of the road closures around DL for my family since they're going to try to find some spots to cheer me on during the race:
Basically red means closed, with Ball road only closed eastbound and Katella closed Westbound, all others both directions. DL and CA are also labeled as well as the start (S) and finish (F). Oh and they didn't mention Anaheim Blvd as a road that's closed, but its part of the course so it must be, so I just put question marks on that section.
I'm going to recommend they use basically drive one block outside of the course to get around, although it looks like Katella eastbound will be open for access to the later miles, you'll just have to take Orangewood to get back, and Ball will be open to get back westbound, but will have to take the road north of that to get east early on. I have different people going to different places, sorry if this is totally confusing.
But hey, thought someone might find it helpful! Oh and about leaving at 4am, I too am staying within a half mile of the start and probably won't show up at the line until around 5. They're just in panic that with LA freeway traffic and the area being so compressed in comparison to DW that thousands of cars are just going to make impossible to get anywhere. Besides which with all those roads closing it'll be rough for those driving in at the last minute. Since you'll already have your number on, you could probably show up even after 5:30 and still make the race no problem, just have to make sure you're warmed up stretched and ready to go.
I'll probably still get up at 4, but just for my breakfast and nerves.
