The crowd support dies down in the second half when the half marathoners finish. A couple aid stations were out of Gu on the second loop, so it might be good to have one or two of your own so you don't go too long without taking in calories.

Perfect sized expo. Can stay warm before race. Well organized. Big post race indoor gathering. Handed out free gloves. Nice medal and finishers cap
Two loop course so you know what to expect second half. Course has some rollers and gradual hills that can take their toll so be careful early on.
