2025 In-Season Challenge
























































SCHEDULE Drivers go head-to-head over five races, with the highest-finishing driver advancing. Bracket seeding is based on best result at Michigan, Mexico City and Pocono.

A 32-driver, single-elimination tournament that takes place over five races on TNT Sports. The driver with the best finish in each matchup advances to the next round.
The first In-Season Challenge race is June 28 at Atlanta's EchoPark Speedway — but there are three seeding races prior that set the bracket itself.
The top 32 drivers in points following the NASCAR Cup Series race at Nashville make up the In-Season Challenge field.
There are three seeding races — Michigan (June 8), Mexico City (June 15) and Pocono (June 22). Drivers are seeded by their best finish in those three races.
The first tiebreaker is the next-best finish in the three seeding races. If two drivers were to finish with the exact same finishing positions over the three seeding races, the next tiebreaker is points standings following the Pocono race.
EchoPark Speedway at Atlanta (32 drivers), Chicago (16), Sonoma (8), Dover (4) and Indianapolis (2).
Simple. The driver in each head-to-head matchup that finishes higher than the other “wins” that matchup and advances to the next round.
A cool $1 million — the ultimate bragging rights.
All five In-Season Challenge races air on TNT, and an alternate broadcast on truTV will focus exclusively on the In-Season Challenge matchups in real time.
