Known as The Last Great Colosseum, Bristol Motor Speedway’s stadium-like structure serves as a versatile multi-use venue that hosts major auto races, football games, concerts and many other captivating events. The sprawling facility has come a long way from its early roots. Today the Colosseum offers guests a wide range of accommodations, from luxurious man cave suites to bar stools in the Busch Banks and Brews Deck to a relaxing environment high atop the track at the Turn One Tavern to a nightclub inside the oval called The Apex. The BMS footprint now includes more than 500 acres of the surrounding area. The 0.533-mile concrete surface features corner banking ranging from 24 to 28 degrees and a pair of 650-feet straightaways. In 2021, the inaugural Karl Kustoms Bristol Dirt Nationals was the first dirt track event held at Bristol Motor Speedway in 20 years.


The goal of the XR Super Series is to complement existing racing schedules with additional opportunities and to reward independent drivers and teams who choose to race these events. Also, starting in 2022, all 25 of these event dates will be officially sanctioned as XRSS races with a newly established rulebook and a full-time, in-house technical inspection team.
The XR Super Series will feature stops at Bristol Motor Speedway (Tenn.), All-Tech Raceway (Fla.), the Dirt Track at Charlotte Motor Speedway (N.C.), Belleville High Banks (Kan.), Stuart International Speedway (Iowa), Gondik Law Speedway (Wis.), the Texas Motor Speedway Dirt Track (Texas) and The Dirt Track at Las Vegas Motor Speedway (Nev.).
