The boys are racin’ again, starting Sunday at Darlington Raceway. NASCAR fans will be revved up all week long as a condensed schedule will see seven races between the Cup Series, Xfinity Series, and the Gander RV and Outdoor Truck Series in just 11 days. The races will happen on only two tracks, Charlotte Motor Speedway being the second, with no spectators allowed on the grounds. Of the seven races, four are in the Cup Series, which means mechanical adjustments will have to be done on the fly as crews shuttle between the two tracks, separated by a little under 100 miles. The green flag waves Sunday at 2:30 PM.
