Race Weekend Schedule and Track Information
Weekend Events and Activities
The Iowa Corn 350 weekend promises three action-packed days of racing, running from Friday, August 1, through Sunday, August 3. The festivities begin Friday afternoon with NASCAR Cup Series practice and qualifying sessions, setting the tone for a thrilling weekend ahead.
Friday night kicks off with the Atlas 150, where the ARCA Menards Series drivers will give fans their first glimpse of competitive action on Iowa Speedway. Saturday's HyVee Perks 250 will be a critical test for teams to assess the track's grip and handling before the main event on Sunday, the Iowa Corn 350.
Iowa Speedway Track Facts
Iowa Speedway is a unique 0.875-mile oval (as measured by NASCAR), though IndyCar records it at 0.894 miles. Dubbed "The Fastest Short Track on the Planet", the track’s design encourages intense, side-by-side racing.
The track features corner banking of 12–14°, a front stretch at 10°, and a back stretch at 4°. Rusty Wallace, who designed the track, explained the thought process behind these specifications:
"It's the only 7/8-mile race track in the country that I'm aware of. When we designed that track, we made it three different banking angles, and those particular angles really created side-by-side racing."
With a 60-foot-wide racing surface, the track allows for multiple racing lines, creating opportunities for drivers to maneuver and overtake. Recent repaving in the corners has introduced varying grip levels, while the straightaways still feature original pavement, complete with bumps leading into turn one. These characteristics, combined with Iowa's unpredictable weather, add layers of complexity for teams as they prepare for race day.
Expected Weather and Track Conditions
Weather plays a pivotal role in NASCAR strategy, as track temperature directly affects tire grip. Dr. Eric Warren, chief technology officer for Richard Childress Racing, has emphasized the importance of these conditions.
Kait Parker from The Weather Channel elaborated on the challenges:
"In NASCAR, track temperature is everything. If the track is too hot, the oil seeps out of the asphalt and it makes it greasy and it's tough for the tires to grip. If it's too cold, the tires can be too hard and then you also have a problem driving. You want a happy medium."
Cooler air can enhance engine performance by increasing air density, while hot and humid conditions can reduce it. Wind also factors into the equation: headwinds create resistance but improve downforce, tailwinds boost straight-line speed but reduce stability in corners, and sidewinds can unsettle cars on the track’s varying banking.
Goodyear’s director of racing, Greg Stucker, shared insights into how the mixed surface will perform:
"Iowa fits into our short track group of tracks from a tire construction standpoint. We were able to hold a confirmation test there just last month, right after the repaving was completed. We learned a lot about the surface and were able to confirm the same tire set-up we raced as the 'Prime' tire in the All-Star race at North Wilkesboro. There will be a lot of grip on the new sections in the corners, but the existing sections down the straightaways still have a lot of character."
Inside the cars, temperatures can climb 30 to 40°F higher than the outside air, pushing drivers to their physical limits. Teams closely monitor weather forecasts to fine-tune tire pressures, engine settings, and overall strategy. The combination of Iowa Speedway's unique surface and ever-changing weather conditions creates a challenging puzzle for teams, where even minor adjustments can make or break race outcomes.
Top Drivers and Race Storylines
Favorites and Defending Champion
Ryan Blaney of Team Penske returns to Iowa Speedway as the defending champion, carrying +425 odds and boasting five stage wins. Blaney’s success last year puts him in the spotlight as he aims to repeat his victory.
Kyle Larson is in the top 3 for winner favorites with +450 odds. Known for his short-track dominance, Larson has consistently delivered top-5 finishes in 2024, further solidifying his position as a strong contender. Reflecting on the upcoming race, Larson shared his enthusiasm:
"I was stoked, you know, I was happy. We've all been wanting a cup race here for a long time".
Denny Hamlin, sitting at +650 odds, leads the Cup Series standings with four wins and 706 points as of July 21, 2025. Hamlin’s prowess on short tracks was evident in his 2024 victories at the Clash at Los Angeles Memorial Coliseum, Bristol, and Richmond. Toyota drivers, including Hamlin, have excelled on short tracks, with 10 wins in the last 18 races at Richmond.
Christopher Bell, another top contender with +385 odds, brings his two-time Xfinity Series wins at Iowa Speedway into the mix. Bell has also shown remarkable consistency, with 10 top-6 finishes in 13 Richmond starts and a win at Phoenix in March 2024. However, Bell expressed some concerns about the track's pace:
"I'm a little bit worried now that the pace is going to be really fast and it's going to be harder to pass. But the speeds are going to be tremendous that's for sure".
While these drivers lead the pack, the race also offers opportunities for rookies and underdogs to make their mark.
Rookies and Dark Horse Candidates
The competition isn’t limited to the favorites - rookies and dark horses are ready to shake things up. Rookie Louis Foster will make his debut on Iowa’s 7/8-mile track, leveraging his Xfinity Series experience to adapt to the Cup Series. With the track’s similarities to Richmond Raceway, Foster and other newcomers might find it easier to transition.
William Byron, a potential dark horse, enters with +800 odds. Despite a winless streak since the Daytona 500, Byron’s strong qualifying performances make him a contender.
Other drivers with value odds include Chase Elliott (+1000), Tyler Reddick (+1400), and Joey Logano (+1400). Each could capitalize on strategic opportunities, such as fuel mileage battles. Among the sleepers, Ross Chastain has struggled recently, managing just one top-23 finish in his last six races. Meanwhile, Chase Briscoe, listed at +1800 odds, secured his fifth pole at the Brickyard 400, contributing to Joe Gibbs Racing’s seven poles this season.
Team Changes and Technical Updates
Team strategies and technical adjustments are set to play a pivotal role in the race. Joe Gibbs Racing has excelled in qualifying, securing seven poles this season. In contrast, Team Penske has faced challenges in this area, despite Ryan Blaney’s status as the defending champion.
Bubba Wallace enters Iowa with renewed energy after clinching a playoff spot and ending a 100-race winless streak. This achievement has bolstered 23XI Racing’s confidence as they prepare for the short track.
Brad Keselowski returns to Iowa Speedway after nearly eight years, reflecting on the familiarity of the track:
"It was hard for me to reconcile the fact that I haven't been here in almost eight years. But when you get here it's like putting on an old shirt. You know how it feels and where to be".
Iowa Speedway, a 7/8-mile short track with 10° banking on the front stretch and 12°–14° in the turns, presents a unique challenge. Teams that fine-tune their setups to handle these conditions may gain a crucial advantage in this inaugural Cup Series event.
