What we know about the IndyCar race taking over the heart of DC

(CNN) — Monaco, Las Vegas, Detroit, and Miami have boasted high-speed street races — and soon, Washington, DC will too.

Race cars will push speeds up to 180 miles per hour this weekend as the nation’s capital joins other iconic cities hosting street circuits, where public roads are converted into a race track. In DC, the Freedom 250 Grand Prix is part of a belated celebration of the nation’s 250th anniversary and President Donald Trump’s continued efforts to transform Washington.

In a first-of-its-kind event for DC meant to cap off a summer of celebrations, more than 200,000 people are expected on the National Mall for the two-day IndyCar race.

The slender, angular four-wheel cars will zip past the US Capitol, make sharp turns around the National Archives, and pass the Smithsonian Air and Space Museum for a total of 147 laps (equal to a 250-mile race to honor the semi-quincentennial). The audio levels at an IndyCar race can reach about 135 decibels. By comparison, motorcycles reach about 88 decibels.

At the helm of the event is Bud Denker, president of the Penske Corporation, who overcame bureaucratic obstacles to map out a race across downtown Washington. The Grand Prix was fast-tracked in January when Trump signed an executive order titled “Celebrating American Greatness with American Motor Racing,” which bypassed congressional approval. Trump is expected to attend the Sunday Grand Prix, according to the White House.

The race comes after a series of events hosted by Freedom 250, a Trump-backed nonprofit tasked with celebrating the nation’s semi-quincentennial. Earlier this summer, the group put on a 16-day “Great American State Fair,” which featured pavilions showcasing every US state and territory, and a youth athletic contest branded as the “Patriot Games” with a grand prize of $250,000.

Penske is planning the race and footing the bill, a similar structure to the Ultimate Fighting Championship event at the White House — Penske and UFC are both sponsors of Freedom 250. The Grand Prix is part of Trump’s plan to celebrate the nation’s semi-quincentennial.

Here’s what else you need to know about the event:

Track layout

The route starts a few blocks in front of the Capitol, along 3rd Street, and is followed by turns onto Pennsylvania Avenue and then 9th Street — passing the National Gallery of Art and National Archives. The route had to include Pennsylvania Avenue — the street where the White House is located and which has a normal speed limit of 25 miles per hour — because it was wide enough to serve as a pit lane.

The course then turns onto Constitution Avenue and cuts across 7th Street, bisecting the National Mall before turning onto Independence Avenue, past the Smithsonian Air and Space Museum. It then turns on Maryland Avenue and back onto 3rd Street, spanning less than 1.7 miles and seven turns.

What is the schedule?

The event takes place over two days, with gates opening at 8 a.m. ET. Saturday’s schedule is dominated by practice sessions before a final qualifying round where drivers will determine their starting positions. A winner will be crowned Sunday at the main event, with post-race ceremonies to follow.

How will DC be impacted?

The race required extensive construction to allow open-wheel IndyCars to race safely at speeds of up to 180 mph. Walls (to protect both racers and spectators) and viewing areas along the track were built — and will need to be taken down after race day. The walls weigh 10,000 pounds, according to Denker, and sit at 1 meter high.

The build-out of the track began at the end of July. Lindsey Appiah, the DC deputy mayor for public safety and justice, told CNN that returning the city to normal after the event will take until roughly the second week of September. While much of the work took place at night, the two-month construction process in the heart of Washington promised to further exasperate commuters and residents in the area whose daily patterns have been disrupted by a busy summer of celebrations.

Denker said some 49 manholes had to be reshaped and smoothed over with silicone to ensure the high-speed cars don’t suck the covers off their place. He praised DC roads for being an ideal track due to their asphalt, vowing to fix any damage to the roads that may occur.

Not everyone is pleased with the extended construction. Elyssa Feder, co-founder and Executive Director of Rising Organizers, a community organizing nonprofit based in DC, said that residents are feeling a “sense of frustration that the administration continues to use the District of Columbia as its playground.”

The airspace above the capital will be impacted as well. The Federal Aviation Administration said it will temporarily pause flights at Ronald Reagan Washington National Airport from 10:15 a.m. to 1:15 p.m. on Sunday, the day of the Grand Prix, though those times may change.

How do I watch?

The full race will be broadcast on Fox Sports platforms for those who want to watch from home.

The event’s free general admission tickets quickly sold out following a May lottery. Penske said the organization received nearly 300,000 requests for the race. General admission attendees are split into the STARS or STRIPES areas associated with their designated ticket zones. Attendees who missed the May lottery for free tickets could attend through suites, which cost $200,000 to $250,000 apiece, though all have been sold, Monumental Sports & Entertainment, one of the race organizers, told CNN.

Who’s driving?

The race features 25 drivers from countries across the world, including Arrow McLaren Racing’s Pato O’Ward, IndyCar’s only full-time racer from Mexico, who told the Indianapolis Business Journal it would be “ironic” if he won given the president’s politics.

Other drivers include this year’s Indianapolis 500 winner, Felix Rosenqvist, and Spanish driver Alex Palou of Chip Ganassi Racing, among others.

What does security look like?

Attendees can expect TSA-style security magnetometer screening and a clear bag policy, similar to the elevated security measures surrounding the July Fourth celebration on the National Mall. The DC government proposed that the event be designated as a national special security event — a status reserved for the nation’s highest-profile and highest-risk gatherings, such as presidential inaugurations and state funerals.

Instead, the race received a special event assessment rating of Level 1 — the highest designation below a national special security event. Denker earlier this summer likened the security to that of the Super Bowl and potentially even higher. While security has been the biggest challenge, Denker said, it’s not a concern for him.

What happens if it rains?

The race will go on rain or shine, unless there is lightning, which would force organizers to delay the event. If there is rain, the cars will be equipped with rain tires. After last month’s “Salute to America” event battled extreme weather and thunderstorms, organizers said there are 10 safe havens designated around the racetrack for spectators.

How much does it cost?

The price tag is more than $35 million, all of it paid for by IndyCar. That makes the over 100-lap race among the most expensive on the IndyCar calendar. Any revenue that exceeds IndyCar’s costs will be distributed to Washington, DC-based charities, organizers said.

The city of Washington is also tapping into a $90 million emergency planning and security fund, which provides federal dollars to accommodate events of this nature, according to Appiah, who anticipates the full fund will be used by the end of summer.

Where else has IndyCar hosted races?

The NTT IndyCar series has brought street races to other cities such as Detroit; Long Beach, California; Arlington, Texas; and Indianapolis.

Will DC museums be damaged by the noise?

The National Gallery of Art, which sits right beside the race’s pit lane, said it conducted an “extensive vibration study” and applied a set of safety measures accordingly to protect guests and collections amid the high speeds of cars.

Will DC become a racing city?

It appears so. Outgoing DC Mayor Muriel Bowser said at a news conference last month she is “very serious” about bringing future races like this to the city as it aims to solidify its sports presence. By 2030, she said, DC will have all of its professional sports teams in city limits, including a brand-new NFL stadium that will serve as the home for the Washington Commanders.

One type of pregnancy-related high blood pressure is becoming more common. A doctor explains

High blood pressure is a common condition that occurs with pregnancy. One form, gestational hypertension, has become substantially more common in the United States, a new report has found.The rate of gestational hypertension increased 73% between 2016 and 2024, and more than 1 in 10 women giving birth in 2024 had it, according to the report published on July 29 by the US National Center for Health Statistics.Why is this condition concerning, who is most at risk, and what can people do to prevent and treat it?To help us understand the findings and what pregnant patients should know about this form of hypertension, I spoke with CNN wellness expert Dr. Leana Wen. Wen is an emergency physician and clinical associate professor at George Washington University. She previously served as Baltimore’s health commissioner.CNN: What is gestational hypertension, and how is it different from other types of high blood pressure during pregnancy?Dr. Leana Wen: Gestational hypertension refers to high blood pressure that develops during pregnancy in someone who previously had normal blood pressure. Clinically, the condition is diagnosed after 20 weeks of pregnancy when blood pressure reaches 140/90 mm Hg or higher on repeated measurements.This form of high blood pressure is one of several hypertensive disorders of pregnancy. Chronic hypertension is high blood pressure that started before pregnancy or is otherwise diagnosed during the first 20 weeks. Preeclampsia is hypertension that develops after 20 weeks and is accompanied by signs that other organs, such as the kidneys, are being affected.CNN: What did this new report find about how common gestational hypertension has become?Wen: The researchers analyzed birth certificate data from all births registered in the United States between 2016 and 2024. Six percent of women giving birth in 2016 were reported as having gestational hypertension. By 2024, that rate had risen to 10.4%. The number of cases increased from nearly 236,000 a year to more than 377,000.The increase was widespread. Rates rose in every age group and every racial and ethnic group studied. Rates also increased in all 50 states and the District of Columbia, though substantial geographic disparities persisted — in 2024, rates ranged from 6.9% in New Jersey to 14.6% in Louisiana.One caveat is that the definition used on birth certificates includes pregnancy-induced hypertension and preeclampsia and is therefore broader than the clinical definition of gestational hypertension.Still, the authors specifically caution that gestational hypertension is probably underreported because health conditions are often underreported on birth certificates. However, the same methodology was used throughout the study period, which strengthens the finding of an increase over time. The overall trend is also consistent with other research showing that hypertension during pregnancy has become increasingly common.CNN: Why is gestational hypertension problematic? What are the potential risks to the baby and the mother?Wen: For the baby, hypertensive disorders are associated with problems with growth, low birth weight, preterm delivery and stillbirth. High blood pressure during pregnancy can also affect blood flow to the placenta. The condition increases the risk of serious complications including placental abruption, in which the placenta separates from the uterus before delivery.For the mother, severe hypertension can damage organs and increase the risk of stroke. Gestational hypertension can progress to preeclampsia, which, in severe cases, can lead to eclampsia, which involves seizures and can be life-threatening.CNN: Who is most at risk for developing gestational hypertension?Wen: In 2024, women ages 40 and older had the highest rate of gestational hypertension among the age groups studied, according to the new report. There was also a strong association with weight before pregnancy. The rate among those with obesity prior to pregnancy was more than double that of people with normal weight. Women carrying twins or more babies at once also had substantially higher rates than those carrying one baby.Rates varied by race and ethnicity as well. American Indian and Alaska Native women had the highest rate, at 13.2%, followed by Black women at 12.3%. These rates may be influenced by multiple factors, including differences in access to healthcare services.CNN: Do we know why rates of gestational hypertension have increased so substantially?Wen: One likely contributor is that some of the factors associated with gestational hypertension have become more common. More people are becoming pregnant at older ages; obesity has become more prevalent among those of reproductive age; and there are more twin, triplet and other multiple births.This, though, may not fully explain the large rise in prevalence, especially as the report found substantial increases across every age and body mass index category. Another explanation is that there could be changes over time in diagnosis and reporting, or there could be other biological factors underlying why this condition appears to be increasing. More research is needed to determine how much of the rise reflects changes in the health of pregnant individuals versus changes in how these conditions are identified and recorded.CNN: How is gestational hypertension detected? Are there symptoms pregnant patients should watch for?Wen: The US Preventive Services Task Force recommends that blood pressure be measured at every prenatal visit. An elevated reading should be confirmed with repeat measurements.Certain symptoms should prompt urgent medical evaluation because they can be signs of preeclampsia. These include a severe or persistent headache, changes in vision such as blurred vision or seeing spots, pain in the upper abdomen, significant swelling of the face or hands, shortness of breath, and nausea or vomiting later in pregnancy.Importantly, though, many people with high blood pressure will not feel any different. That means someone should not assume that because they feel well, their blood pressure must be normal. Pregnant patients should know their usual blood pressure and ask their clinician about it during clinic visits.CNN: How is gestational hypertension treated if it develops?Wen: Treatment depends on how high the blood pressure is, whether there are signs of preeclampsia, and how far along the pregnancy is and how the baby is doing.Someone with gestational hypertension will need more frequent monitoring, which may include home blood pressure measurements, blood and urine tests, and additional monitoring of fetal growth and well-being. Some people may require blood pressure medications.Severely elevated blood pressure accompanied by signs of organ damage may require early delivery. In some cases, clinicians have to weigh the risks of continuing the pregnancy against the risks of delivering early.CNN: Is there anything patients can do before or during pregnancy to reduce their risk of developing gestational hypertension and other hypertensive disorders of pregnancy?Wen: Some risk factors, such as age or carrying twins, cannot be changed. But optimizing health before pregnancy can help reduce risk.People who are planning pregnancy should make sure that existing conditions such as chronic hypertension and diabetes are well-controlled. Those who have overweight or obesity can discuss with their healthcare provider whether weight loss before pregnancy would benefit their health. Regular physical activity, a nutritious diet and not smoking are essential for cardiovascular and overall health generally.CNN: What should people who have had gestational hypertension know about their health after pregnancy?Wen: In the immediate term, they should know that delivery does not immediately eliminate the risk. Blood pressure problems can persist or worsen in the initial days and weeks after childbirth, and preeclampsia can first appear during the postpartum period.Patients should also be aware that hypertensive disorders during pregnancy are associated with an increased risk of developing chronic hypertension and cardiovascular disease later in life. People who have developed hypertension during pregnancy should make sure that this remains part of their medical history so that future primary care providers and other healthcare professionals are aware of this potential risk factor.The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
