Hot Summer Nights Series (Muddy Creek Raceway)
Toyota of Kingsport Hot Summer Nights Series, run by Victory Sports Racing at Muddy Creek Raceway (MCR) in Blountville, TN, the promoter's home track and also the base of the THOR United States Mega Series, the AMA Tennessee State Championship and the Top Gun Showdown. Distinct from the unrelated 'Hot Summer Nights' series run by Miller Motorsports in Mississippi and Alabama, which has no Tennessee rounds. Victory Sports runs several of its points series concurrently on the same race day at MCR (HSN alongside the BIG, COS, Mega and Ultra series, plus one-off 'Moonlight MX' racing). Round numbers run up to at least Round 17 for the 2026 season, but they do not map one-to-one onto Victory Sports' own published 2026 MCR calendar, which lists only seven HSN-tagged race dates for the year (some, like the Aug 22-23 Saturday/Sunday pair, evidently carrying more than one numbered round). The dates follow that calendar, and the season closes with Round 16 on Oct 24 and Round 17 on Nov 7, billed as the series' last Muddy Creek dates of the year.
