Many people say that you should try to drive the course you'll be running to get a feel for what to expect.
Since I'll probably not be visiting San Diego before race day, this seemed pretty impossible until, lucky me stumbled on something even better - VIDEO!
I had no idea that this existed but after kicking around the SD RNR site for a bit - found it.
Some of it looks city-ish and the highway looks slightly boring but all in all it seems I'll have a lot to look around at as I run. For better or worse I am signed up and California here I come!!
