This is great race! The location is fantastic because it's not just flat paved road, which Chicago is pretty well-known for. The crushed limestone is really nice to run on and I like that it is very hilly. It is also organized well but I do see 3 drawbacks.

1) Why is this in July?! It can get really hot. We were actually pretty lucky this year to not be overly hot.
2) They could really use extra aid stations, especially if it was to be hot. Even this year where it wasn't horrible, I brought water with me because it would have been too difficult otherwise.
3) The run through the grass wouldn't be all bad, but it is not mowed before the race, and so you have to try to run through some really tall grass which is very difficult.

But again, I do not want to take away from it's greatness. I would definitely do this race again!
