"Run Home Chicago" is a 5K run and walk kicking off from Soldier Field. The event helps to raise money for services and shelters to help those that need it.
Participants took part in either a 10K run, 5K run or a 5K walk. Children were also able to join in the Kids Dash.
The organization has already raised close to $70,000 for the cause, but with the number of homeless people in need of help on the rise, it is a big mission.
Tens of thousands of homeless people and families live throughout the Chicago area. The latest figures by the Chicago Coalition for the Homeless shows the rate is close to 5.5 percent.
A number of local celebrities, including some Chicago Bears, Cubs and Bulls were on hand Sunday to show their support.
"Lot of homeless people in the city of Chicago, and to be a part of this is truly a blessing. I came out to help and am ready for anything. I'm just proud to be here," said Chicago Bear Earl Bennett.
ABC7's John Garcia was also participating.
Chicago Mayor Rahm emanuel and his wife were honorary chairs for the event.
