William Byron ends barren run and retakes the lead in the championship.
After a 22-race victory drought, Hendrick Motorsports driver William Byron expressed a need to win a race, ultimately triumphing at the NASCAR Cup Series in Iowa.
Despite starting the 2025 season with a Daytona 500 win, Byron had struggled to replicate that success, while teammates Chase Elliott and Kyle Larson thrived.
Breaking through at Iowa Speedway, Byron pushed his limits in a fuel-conscious race to defeat Chase Briscoe by 1.1s and regain the championship lead.
The victory was a crucial milestone for Byron, who had faced eight challenging races with only two top 10 finishes leading up to Iowa.
Byron admitted the win was a significant relief, boosting momentum for his team after consistently strong performances throughout the season.
