The 2023 Polar Plunge takes place at Chicago's North Avenue Beach, sending thousands of participants -- many in costume -- sprinting into frigid Lake Michigan water, all for a good cause.
The annual event raises funds for the Special Olympics Chicago.
The fundraiser, which is in its 23rd year, was designed to support the more than 7,500 Special Olympics athletes who compete year-round in Chicago. Last year, more than $1.6 million were raised. This year is on track to match, if not beat, that number.
The winter tradition is "historically the largest and most well-known plunge event," according to its website, with nearly 4,000 participants expected to participate.
For those looking to support a loved one, friend or even an NBC 5 reporter, you can watch it all live this weekend right here.
The opening ceremony is set to begin at 9:45 a.m. Sunday, with the first waves of plungers dipping in around 10:30 a.m.
