Overview

• The inaugural NASCAR In-Season Challenge culminates at Indianapolis Motor Speedway as Ty Gibbs and underdog Ty Dillon vie in the Brickyard 400 for a $1 million bonus
• Gibbs, who has posted six top tens and four top fives this season, said his sole focus is on winning the race rather than securing the tournament’s prize
• Joe Gibbs Racing’s competition director Chris Gabehart has resumed pit road duties to refine Gibbs’s tactics on the narrow 2.5-mile oval known for limited passing
• Dillon, the 32nd seed who upset top drivers including Denny Hamlin and Brad Keselowski, aims to replicate the success of his last win at Indianapolis in a 2014 Xfinity race
• Denny Hamlin cautioned that Indianapolis’s technical layout may favor pure car performance over Dillon’s upset-driven approach
