The term “mid-Ohio” might not bring much excitement to mind: rolling hills? Livestock? Butter-churning contests? Not so thrilling. (Well that last one, maybe.) But surprisingly, the region is home to one of the greatest, fastest tracks in the states, a 2.4mi, 15-turn circuit that hosts both the IndyCar and NASCAR Xfinity Series. Unlike most tracks on our list, Mid-Ohio hosts its own courses, called the “Mid-Ohio School,” where there are a variety of levels of instruction, from open lapping to three-day race courses.
