Blue + Black is what is shown by the Village of Pleasant Prairie (13.9 miles)
Blue + Red is what is now shown on the Trek web site (12.4 miles)
(My guess, right now, is that as a race director I would strongly push for the shorter route shown on the Trek web site. I suspect this is what will ultimately be set for race day, but I will feel a lot more comfortable getting the Village to confirm it. They're responsible for closing the roads, after all!)
