MRN is one of the two main radio broadcasters of the NASCAR Cup Series and Xfinity Series, covering events held at tracks owned by NASCAR, along with Pocono Raceway and World Wide Technology Raceway.

In addition to NASCAR races, MRN broadcasts the majority of the ARCA Menards Series and once had exclusive coverage of the United SportsCar Championship (IMSA now does the radio broadcasts) and Formula One, including the United States Grand Prix, which returned in the 2012 season at the Circuit of the Americas in Austin, Texas and offers other race related programs.

The MRN flagship station is WNDB, which serves Daytona Beach, Florida.

Three MRN announcers also host daily call-in shows on Sirius XM NASCAR Radio channel 90 year round.
