Performance Racing Network

The Performance Racing Network (PRN) is a radio network controlled by Speedway Motorsports.

Since 1981, PRN has aired all NASCAR-sanctioned Sprint Cup and Xfinity Series events held at Speedway Motorsports-controlled tracks which include Atlanta, Bristol, Charlotte, Kentucky, Las Vegas, New Hampshire, Sonoma and Texas, along with the Indianapolis Motor Speedway, where they co-produce and syndicate (in non-conflicting markets with the IndyCar Radio Network) for the Brickyard 400, where their staffers work both races. This is in contrast to other NASCAR events (operated by ISC, Dover Motorsports and the Mattioli family), which are broadcast by ISC-controlled Motor Racing Network. PRN and MRN on most occasions share the same radio affiliates (IMS also, although PRN jointly produces the IMS race) in order to broadcast a complete NASCAR schedule.

All PRN shows with the exception of the pre and post race shows originate from Performance Racing Network's studios at Charlotte Motor Speedway.
