Super flat course if that's what you're looking for. Excellent fan support. Good sized expo and I got to meet Katherine Switzer! Finishing on the Illini football field is fun. Using the U 0f Illinois campus for expo and race start made parking (free) a breeze. Some bad road conditions especially in the campus and the course while pleasant isn't scenic.
The course is very flat. A runner should be able to settle into a consistent pace and if the weather cooperate (it did in 2013) a PR can be accomplished here. Plenty of aid stations and 4 gel stops. Every water stop was organized differently unfortunately. Uniformity is so important late in a race when fatigue sets in.
I camped so I can\'t comment on host hotels but I did take advantage of the shower option after the race in the University recreation center and that was excellent. Plenty of free parking on the stadium parking lots.
