Vrooom! Vroooooom! Saturday the brand new, not really finished Formula 1 race track opened its gates to runners, joggers, and walkers to take a tour of its 3.4 mile loop. Known as the Circuit of the Americas, it’s the only Formula 1 track in the United States. With the inaugural F1 race taking place in 2 weeks, RunTex put on this fun run giving special access and a preview of the course before anyone else.
