I ran this event in 2008 so be aware this is probably dated as to the current incarnation of the event...
Positive -
Well run race for the number of runners involves. Waves were spread out and volunteers and entertainment (not everyone had ear buds with iPods (haha) in those days!) long the route was as good as I have been a part of.
Neutral -
So the big unique (for me) part of this run was going to be the loop around the Motor Speedway where the 500 car race is held. At the risk of sounding negative... in actuality this was not interesting in practice. At all. And of course no shade. Much preferred the other portions of the course.
