Just ran the half marathon this past weekend. Some comments:
* I didn't do the packet pickup, but heard it was super easy to pick up. Very well organized and easy in and out. (This is unlike the Hot Chocolate race I did in Chicago last year, which was a nightmare of all nightmares)
* Parking on race day was super easy. We parked maybe a quarter to half mile from the starting line. There were enough porta-potties to take care of runners and spectators.
* I didn't like running through the park -- Not sure what the park was called, but the running path was rather narrow and I couldn't stretch my arms without hitting somebody. I would recommend a path that would take up more streets, but I also realize this impacts the local community at the same time.
* I didn't care too much about all the twists and turns near the end of the race. There was at least one 180 degree turn and maybe another 90 degree turn. A straight shot would be nice.
* Excellent use of the football stadium. If you're a big Illini fan, this is a huge rush to finish on the football field.
I'm not sure if I'll run this course again as there are plenty of other options in Northern Illinois, but it's not a bad race in late April.
