There are a few of these outfits in Chicago burbs.
They are bad news and not connected with any local running clubs. They put these events on like they are on tour. Schaumburg forest preserve marathon today. Deer Park shopping mall the next week, Naperville river path half after that, etc etc.
Their M.O. is:
1. Have the race on a bike path or forest preserve or shopping mall access roads before hours ( no need to pay cops at intersections )
2. Have a link on your registration page to a charity allowing you to donate in the name of the race
3. Don’t disclose how much is given to charity
4. Solicit volunteers to help you run your business
5. Cheap prizes ( and not always given out).
I have no idea what rules are around conducting business on county property but maybe they know people.
