They have a 5K and a 10K race on the same morning. It's a very flat but scenic course through Oak Park. You run by some Frank Lloyd Wright houses, hence the name of the race. There is plenty of parking nearby for those commuting from outside the Oak Park River Forest High School neighborhood. There are some booths and tents at the end, and the food/drink provided at the finish is fine. The t-shirt is a long-sleeve cotton shirt. This is a great course to try and set a PR!
