One of the things I find odd with the run course is that we only do Wellington 1x. Per the course description we do Wellington, then hit the canal, and then don't do Wellington again for the 2nd loop. They could easily turn around sooner at Dow's lake (or even just skip it and turn around at Bronson), or turn around sooner on Col. By.

It seems to me that if you're looking to show off Parliament, Supreme Court, etc, you'd do it for both loops since you need it closed for most of the race anyway.

The only thing I can think of is that if you only have it for 1 loop, you can re-open that section sooner - but I don't think they're closing Portage anyway.
