This is a gorgeous trail for the entirety of the race. However, bring your own food as although there are regular fluid stations, there is only minimal food provided. Also, you go past the finish line and have several more miles which can be disheartening! Overall though a really nice course and a beautiful area.

Cool, beautiful weather on gorgeous trail in national park. Flat as can be. Most of run on crushed limestone path which is easier on the joints. Relatively small and friendly.
If you need a lot of crowd support, this isn't your marathon. Crowd is enthusiastic but sparse.
