@Publisher although the UMich verbiage says otherwise, I agree with you that the more mileage on a shorter track isn’t good for your body, because turning and the banking will present angular issues that your ankles, knees, hips, back, neck, etc. will have to compensate for. I’m sure that’s why NASCAR and Indy race cars change their tires often during their races as well as setup their cars specifically for embankment racing.
Regarding NU and their new facility, it’s a wealthy private school, would you expect anything differently? ? Hopefully, the new facility will help NU become more competitive in all sports.
