NASCAR In-Season Challenge Picks: My Best Bets Today

Now that you've claimed the best NASCAR In-Season Challenge betting promos, it's time to make your picks. Here are my best bets, featuring picks for the first round and the outright winner.

Brad Keselowski Over Kyle Busch (+100): Brad Keselowski has long been one of the elite superspeedway drivers in the Cup Series. He has recorded two finishes of sixth or better at Atlanta since the beginning of 2023. While Kyle Busch has also been strong at Atlanta, I trust Keselowski’s Ford, as Fords have been the superior manufacturer on superspeedways.

Erik Jones Over Ross Chastain (+160): Both Ross Chastain and Erik Jones have performed well at Atlanta since it transitioned to a superspeedway. Chastain likely holds a slight edge in this matchup, but I believe this number is too long for Jones. He’s been running much better lately and should be in a strong position to take down Chastain.

Chase Elliott to Win (+1400): Chase Elliott is my top pick to win the NASCAR In-Season Challenge. These tracks line up well for him, as he’s an elite road course racer—important for rounds 2 and 3. He’s also one of the best drivers at Dover. While his record at Indianapolis is solid, his potential at the other tracks makes me especially high on Elliott for this tournament.

Daniel Suarez to Win (+5000): While evaluating the NASCAR In-Season Challenge, Daniel Suárez stood out as a surprise contender. He’s a former winner at Atlanta, so I expect him to advance from round 1. In my bracket, he would face Joey Logano and Denny Hamlin in the following rounds. While both drivers are generally stronger than Suárez, neither excels on road courses—where Suárez is solid. If he makes it to the final four, you’d be holding a +5000 ticket, and from there, anything can happen.
