An estimated 50,000 runners from across the world will take to the streets of downtown Chicago in just over a week's time for the 2024 Bank of America Chicago Marathon.

This year's event will attract spectators from near and far - plus bring the potential for more records to be broken.

As the race nears, here's everything runners, visitors and Chicago-area residents should know:

Who is running the 2024 Chicago Marathon?

This year's marathon will feature past champions and exciting marathon stars as organizers unveiled this year's elite athlete lineup.

The lineup is highlighted by two of the "10 fastest women of all time, two of the world’s most exciting marathon stars racing in the United States for the first time and both defending champions in the wheelchair field."

“We are accustomed to making history at the Bank of America Chicago Marathon,” Executive Race Director Carey Pinkowski said in a statement. “With some of the fastest athletes in the world joining us this fall, we are hopeful to build on the tradition of great performances this year.”

Which records might be broken at the 2024 Chicago Marathon?

After setting an attendance record in 2023, marathon organizers have once again announced the field of runners could make history.

Organizers have said that an estimated 50,000 runners are slated to toe the starting line in downtown Chicago, a number that would break last year's record of 47,000.

“The 2023 Bank of America Chicago Marathon was record-setting across the board from historic performances and countless personal bests to record-breaking participation and charity fundraising,” Executive Race Director Carey Pinkowski said in a statement. “The energy and excitement of race day captured the attention of runners from around the world and we’re humbled by the extraordinary interest we’ve seen as a result. We look forward to welcoming a new field of participants in 2024 and once again putting on a race that unites the local and global running communities on the streets of Chicago.”

There's also some speculation a women's American record could fall, with Keira D'Amato and Betsy Saina both in the lineup.

D'Amato, the former American marathon record holder, will return to the starting line after being part of the broadcast team for the past two years.

“I have a special history with the Chicago Marathon,” said D’Amato who finished fourth in 2021. “The past two years I’ve run my mouth in the lead vehicle for NBC. I’m excited to get back to running my legs.”

D'Amato first broke the American marathon record in 2022 in Houston, topping a time that had stood for 16 years.

Emily Sisson broke that same record shortly after during the 2022 Chicago Marathon. D'Amato was among the long line of legendary female runners celebrating Sisson at the Chicago finish line that year.

Saina, who placed fifth in this year’s Tokyo Marathon, will look to record her first Chicago finish after dropping out of the race in 2019 due to illness. She's run the third-fastest marathon time of any American woman, one spot behind D'Amato.

Sara Hall and Emma Bates are also in the field for the Americans. Hall's best time of 2:20:32 comes from Chandler in 2020. Bates ran her best time in 2022 at the Boston Marathon with a 2:22:10 finish.
