AdventHealth 400

Kansas Speedway has quietly become one of the best intermediate tracks on the Cup Series schedule. The 1.5-mile D-shaped oval opened in 2001 with uniform 15-degree banking, but the 2012 repave and the addition of progressive banking — from 17 to 20 degrees — transformed the racing surface into a multi-groove playground that rewards drivers who can hunt for grip across the width of the track. Over the last decade, Kansas has produced some of the closest finishes in NASCAR history, including Kyle Larson's 0.001-second victory over Chris Buescher in the 2024 spring race, the closest finish in modern Cup history. The repaved surface takes rubber quickly, and by lap 40 of a run, the outside lane becomes the preferred groove as tire wear opens up the top. Joe Gibbs Racing and Hendrick Motorsports have traded dominance here in recent seasons, with Denny Hamlin, Kyle Busch, and Kyle Larson all logging multiple wins. The AdventHealth 400 is a 267-lap test of long-run speed and short-run restart aggression, and the winner almost always comes from the top five in the closing stage.
