A weekend of speed at Chicagoland
Chicagoland Speedway in Joliet, Illinois, is set to host a doubleheader that pits the premier NASCAR Cup Series against the developmental O’Reilly Auto Parts Series in back‑to‑back events, offering fans a rare chance to see top‑level stock cars and rising talent on the same weekend.
Saturday’s O’Reilly Auto Parts Series race will kick off at 5:30 p.m. Eastern Time and will be televised on The CW, while the following day the Cup Series takes the track at 6 p.m. ET, broadcasting on TNT Sports. The schedule places both races in prime viewing hours, maximizing audience reach across the United States.
Team preparations differ markedly in terms of tire strategy. Cup Series entries are granted twelve sets of tires for the entire weekend, whereas O’Reilly Auto Parts Series competitors receive seven sets. This disparity forces crews to balance aggression with conservation, shaping the on‑track dynamics for each race.
Beyond the on‑track action, the weekend’s coverage will include detailed qualifying order reports, practice speed charts, and post‑race results, giving viewers a comprehensive picture of performance trends and emerging storylines throughout the event.
