The 2026 NASCAR Cup Series hits North Wilkesboro Speedway this weekend, and so does the In-Season Challenge.
With three rounds completed, just four drivers now remain in the hunt for the $1 million prize fund, which will be awarded after next Sunday's Brickyard 400 at Indianapolis Motor Speedway.
With that said, let's take a look at those four drivers and who matches up in North Carolina this time around.

NASCAR In-Season Challenge Round 4
Todd Gilliland vs. Chase Elliott
The first In-Season Challenge matchup this weekend sees Todd Gilliland go head-to-head with Chase Elliott.
Not many would have predicted Gilliland would get this far in the challenge, but he has beaten a host of drivers in better machinery on his way here, including Elliott's Hendrick Motorsports teammate Alex Bowman in Round 3.
This week, Gilliland even signed a contract extension with Front Row Motorsports, so his confidence should be as high as it possibly can be heading into this matchup.
Still, Elliott heads into this one as the firm favorite to progress. He's the better driver, has far more experience, and has a better car underneath him.
Everything points to Elliott progressing to the final two, but we'll find out one way or another on Sunday night.
Christopher Bell vs. Ryan Blaney
The winner of Gilliland vs. Elliott will take on whoever comes out on top between Christopher Bell and Ryan Blaney for the $1 million prize at Indianapolis next weekend.
Unlike the previous matchup, where Elliott is considered the strong favorite, this one is truly a 50-50 and could go either way.
Blaney enters Sunday's race fresh off the back of last Sunday's win at Atlanta, and also starts from pole position after qualifying was canceled and the lineup set as per the rule book for the Window World 450.
Bell, though, has finished second in the last two races and was fastest in Cup Series practice on Saturday evening.
Whoever comes out on top in this matchup may well turn out to be the race winner, never mind progress to Round 5.
