Following Bubba Wallace's emotional Brickyard 400 victory that snapped his 100-race winless streak, the NASCAR Cup Series is at Iowa Speedway on Sunday for the running of the Iowa Corn 350. This will be the 23rd race of the season, giving drivers only four opportunities to solidify their playoff positioning.
This will only be the second Cup Series race at Iowa after Ryan Blaney's win last season, which also made him the only driver with a win in all three series at the track. Coming into the weekend, the top four in the standings (Chase Elliott, William Byron, Kyle Larson, Denny Hamlin) are only separated by 20 points, while RFK Racing teammates Chris Buescher and Ryan Preece head into the race separated by 42 points for the 16th and final playoff spot.
So, let's dive right into the Iowa Corn 350 with the starting lineup as well as all the info about the TV broadcast, start time and more that fans need to know ahead of the green flag.

Briscoe narrowly beat Byron for the top spot by 0.084 seconds, with Larson, Team Penske's Austin Cindric and RFK Racing's Brad Keselowski rounding out the top five.
Blaney, Carson Hocevar, Elliott, AJ Allmendinger and Justin Haley completed the top 10. Notables outside the top 10 include Hamlin (11th), Joey Logano (14th), Wallace (15th), Alex Bowman (16th), Christopher Bell (17th), Tyler Reddick (22nd), Buescher (27th), Ross Chastain (28th), Preece (33rd) and Kyle Busch (37th). Busch made significant head-on contact with the outside wall in Turn 1 during practice and completed the 17th-fastest lap before the crash. The team confirmed on social media that Busch will be in a backup car on Sunday.
There's big trouble in practice for @KyleBusch.

NASCAR race start time: When does the Iowa Corn 350 green flag wave?

Iowa Corn 350 stages explained
Iowa Corn 350 Stage | Lap Number When Points Awarded |
|---|---|
Stage 1 | 70 |
Stage 2 | 210 |
Final Stage | 350 |
For those who don't know, most of the points for the season-long NASCAR Cup Series standings will be awarded for the final stage. Stages 1 and 2, though, give teams two additional opportunities to score points, as well as extra breaks for pit stops (and for the TV product, commercial breaks).
Ten points go to the stage winners, and the remainder of the top 10 receive points in decreasing order with the 10th-place finisher getting one point. The stage victories and additional points can prove valuable throughout the season as drivers try to qualify for the 10-race playoffs that begin at Darlington Raceway on Aug. 31.
