I did this race last year and was really excited because it was at Mission Bay/Tecolote. The course was a little cramped with runners going toward mile 2 and back to finish line on the same sidewalk. I almost got elbowed in the face on my way to the finish line. There wasn't enough space for people to run next to each other and also have room for the walkers on the same path. I don't remember them having aid stations out. It was fairly flat though.
