Have you checked the NB high school? I live in Oak Creek and the track has hours that its open to the public. I've also run on the track at Brookfield Central.

When I was in high school I used to run at my track. I guess I just always thought hs tracks were open to the public.

And then there is always the Pettit Center.

Beauty of Tracks in SE Wisconsin is (or was when I lived there) that as long as there isn't practice or a game going on you have free roam of the track. And even if there is practice or gym class the teacher/coaches will often ask you if you would like lane one. (Experienced this many times at both Arrowhead's track and Shorewood's track).

Wauwatosa West HS near Hwy100 and Center St, there is a track in West Allis 92nd St and Cleveland it is paved with blacktop.
As mentioned the Pettit Center (get info on the track length). Don't know if you can in at Marquette.

yeah that's right near my house. Always open.

The pettit is like 443 meters or something.
