You really can't beat running over the ambassador bridge into Canada right at sunrise, while the Canadian customs officers blast "Blurred Lines" and offer you very enthusiastic high fives. Running back through the underground tunnel makes you feel a little like you're going to die (although I will admit, the fact that I was getting flashbacks of being 19 and hungover driving back from Canada might have contributed to that), but emerging on the other side to the sunshine and a huge crowd makes it all worth it.
All-in-all, great race. Really fast, flat course, with the exception of the bridge where it gets a little clogged up from people walking up the incline and taking selfies. Pretty good crowd support--but in my opinion the Canadians were the best supporters of them all (step yo game up, Detroit!). The course takes you through a lot of the Detroit neighborhoods. I grew up about half an hour from Detroit in the burbs, but never got to see a lot of it, so getting a tour of it while running was pretty cool. Later in the race you cross over onto Belle Isle, which is very scenic. I had someone warn me before that race that it would be windy on Belle Isle--they were right. Without the buildings to block the wind you get quite the breeze.

Parking is a little bit of a pain--there's nothing super close to the start/finish, so get there early, and expect to hobble for a bit after or plan on taking the People Mover.
