I ran it last year and the temp was perfect, about 58 degrees with no sun and a slight drizzle.
The course is all flat and is out and back. It is a paved trail next to the highway - so you have trees on one side and the highway on the other side! There are water stations throughout which makes it nice because on the way back through you know exactly where the water will be! at the half way (turnaround) there is water also. If I would have trained for this marathon I probably would have BQ'd, but instead I ran in October and was 2 mins from qualifying and then just decided not to run before this race. (very bad idea!) Even without training at all, I still ran it in less than 4 1/2 hours.
Overall Great experience and hope to be even better this year!
