They are protesting two alleged racist incidents blamed on some of their classmates and staff.
The student walkout comes, as the IHSA investigates reports of racist behavior and comments from Lincoln-Way East High School students and staff.
In a statement posted to social media, three cross country student athletes from Homewood Flossmoor described overhearing the coach at Lincoln-Way East refer to them as "monkeys" before a meet on Saturday.
Video from the day before, on Friday, shows five Lincoln-Way East students making monkey gestures and sounds toward the Homewood-Flossmoor crowd. ABC7 has blurred the video because those involved are believed to be minors.
Lincoln-Way East issued an apology about Friday's incident, calling the behavior "egregious and intolerable,"
The school said what happened on Saturday was innocent, explaining in part, "Lincoln-Way East coaches merely recounted a well-known story about an area of the Lyons Township course referred to as "the jungle."
The Lincoln-Way administration is confident that neither its staff nor student athletes intended to harass, intimidate or offend any of their competitors or those competitors' families."
Ocean Myrick is leading a student walkout today to take a stand against what she says is clear racism, in the hopes change will be on the horizon.
"They sit here and they claim, 'oh, they don't condone racism. They don't condone this.' But racism is one of the loudest things and biggest issues I've done seen in that hall in general," Myrick said. "I was even scared at one point to walk them hallways by myself...We will always have history that repeats itself. But all we could do is try."
ABC7 has been told the walk out will happen at the beginning of fifth period Wednesday around 11:50 at Lincoln-Way East.
Meanwhile, the school has not shared any details on disciplinary action against the students involved in the incidents.
