Washington D.C. is buzzing with the sound of engines as IndyCar drivers took to Pennsylvania Avenue for practice laps ahead of Sunday's Freedom 250 Grand Prix. The 1.7-mile temporary circuit winds through the heart of the nation's capital, passing iconic landmarks like the Smithsonian museums on the National Mall and offering views of the Capitol building.

President Trump, who initiated the order for an IndyCar race in D.C., is scheduled to drive his armored limousine, "the Beast," on the track on race day. He will also officiate the start of the race by waving the green flag, marking a commemoration of the nation's 250th birthday. Bud Denker, president of Penske Corp., the race's organizing body, confirmed these details.

The race will feature 147 laps, with drivers expected to reach speeds exceeding 170 mph on the tight street course. First Lady Melania Trump is also expected to attend and join the president in the viewing stands. Over 100,000 spectators are anticipated to attend the event.

Organizers have implemented extensive safety measures, including barricades and secured manhole covers, to protect both participants and the public. Residents have experienced road closures for weeks due to the track's construction. High-profile sponsors, such as Delta, Gulfstream, and Verizon, have luxury suites available for $250,000, while "Champions Club" members can purchase tickets for $5,000 for prime viewing locations. Boeing, SpaceX, and Starlink are also listed as race sponsors.

Free tickets were distributed via a lottery in June, and aerial flyovers are planned for Sunday's event. The race is scheduled to begin at 1:10 p.m.
