I ran it in 2016 for my first.
No hills really to note, hilly, but nothing like mile 9.
The road near the Colonial has a crown in the middle and they don't shut off traffic very well. Lots of people leaving their houses, etc.
After the Colonial, almost no support at all going through the park. Bikes, strollers, etc.
Wangus is right, Aid stations are great and nicely spaced.
I really can't compare it to others, but I enjoyed it. I'm doing the half and probably not for time if you want a pacer.
