The 2026 NASCAR In-Season Challenge kicked off at Sonoma Raceway on Sunday, with 16 drivers now having been eliminated from the $1 million competition.

Among those 16 drivers, some of the biggest names to fall were 23XI Racing stars Tyler Reddick and Bubba Wallace.

Reddick and Wallace were matched up against Alex Bowman and Michael McDowell, respectively, at Sonoma, but neither driver was able to get the better of their competition. Reddick finished 36th compared to Bowman's 10th place, while Wallace's 22nd was not enough to beat McDowell's 9th.

Let's take a look at the full results from the first round at Sonoma below.
