NASCAR’s In-Season Challenge makes its debut this weekend at EchoPark Speedway, the track formerly known as Atlanta Motor Speedway.
Thirty-two drivers were seeded based on their best finish in the last three weeks (Michigan, Mexico and Pocono).
The drivers were paired based on those seedings. The driver who finishes the best in his matchup advances to the next round.
The second round (16 remaining drivers) is at the Chicago Street Race. The third round (eight remaining drivers) is at Sonoma. The fourth round (four remaining drivers) is at Dover. The final round (two remaining drivers) is at Indianapolis.
The winner will collect $1 million.
Here is a look, with the the help of Racing Insights, at the first-round pairings:
No. 1 Denny Hamlin vs. No. 32 Ty Dillon
Hot streak: Denny Hamlin has finished in the top three in each of his last three starts this season.
Long odds: The last time Ty Dillon finished ahead of Denny Hamlin at Atlanta was March 2017 when Dillon placed 15th and Hamlin was 38th — well before EchoPark Speedway ˜was reconfigured and became a drafting track.
Winner ... advances to meet winner of Kyle Busch - Brad Keselowski matchup.
No. 2 Chase Briscoe vs. No. 31 Noah Gragson
Fun fact: James Small, crew chief for Chase Briscoe, has 95 career top-10 finishes. Noah Gragson will be making his 93rd career Cup start this weekend.
Former teammates: This is the only first-round matchup involving former Cup teammates. Both raced at Stewart-Haas Racing in 2024.
Winner ... advances to meet winner of Ryan Preece - William Byron matchup.
No. 3 Chris Buescher vs. No. 30 Todd Gilliland
Third time a charm for Buescher? Todd Gilliland has finished better than Chris Buescher in the last two races at a drafting track. Gilliland was 16th at Talladega and Buescher was 34th due to an accident. At Atlanta in February, Gilliland placed 15th, while Buescher was 30th after his car was damaged in an incident.
Strong start: Chris Buescher has nine top-10 finishes this season in the first 17 races. That’s his most top 10s through the first 17 races of a Cup season.
Winner ... advances to meet winner of Zane Smith - Austin Cindric matchup.
No. 4 Christopher Bell vs. No. 29 Ricky Stenhouse Jr.
Familiar face: This is a matchup between spotter Tab Boyd’s former driver (Ricky Stenhouse Jr.) and his new driver (Christopher Bell). This will be Boyd’s first race with Bell.
See ya in Victory Lane: These two have combined to win two of the last four points races on a drafting track. Bell won at Atlanta in February. Stenhouse won at Talladega last fall.
Winner ... advances to meet winner of Ross Chastain - Erik Jones matchup.
No. 5 Chase Elliott vs. No. 28 Austin Dillon
Dominant: Chase Elliott has finished better than Austin Dillon in 13 of the 17 points races this season, including six in a row.

No. 8 Alex Bowman vs. No. 25 Joey Logano
Better days ahead? Since winning at Atlanta in last year’s playoff race, Joey Logano has finished 33rd or worse in three of the last four races on drafting tracks. The exception was a 12th-place result at Atlanta in February.
Close duel: Alex Bowman has finished better than Joey Logano in nine of the 17 points races this season.

No. 10 Kyle Larson vs. No. 23 Tyler Reddick
Good time for a win: Kyle Larson is winless in 50 Cup starts on a drafting track. Also, Larson’s five-race winless streak entering this weekend is tied for his longest of the season.
In need of a turnaround: Tyler Reddick has one top-10 finish in the last nine points races.

Looking to improve: Michael McDowell has one top-10 finish in his last nine races on drafting tracks, dating back to last season.

No. 12 John Hunter Nemechek vs. No. 21 Josh Berry
Opposite directions: John Hunter Nemechek comes into the weekend off back-to-back sixth-place finishes. He has four top-10 finishes in the last seven races. Josh Berry has one top-10 finish in the last 12 races.
