Hosted by the Chicago Department of Aviation (CDA) and United Airlines, the event raised funds for the Wounded Warrior Project, which provides programmes and services to meet the needs of injured service members.
The runners’ and walkers’ route was the new Runway 10C-28C, constructed as part of the O’Hare Modernization Program (OMP) on the south airfield and due to open to air traffic on October 17.
The races had more than 650 runners and walkers in the 10K run; nearly 2,500 in the 5K race and almost 200 children for the kids race.
CDA commissioner, Rosemarie Andolino, said: “This was a great event for the community to see the operations at O’Hare first hand.
“I thank United Airlines and all of our sponsors for partnering with us to host this great event to raise money for the Wounded Warrior Project.”
A free outdoor community day festival was held throughout the afternoon, featuring food vendors, live music, family activities, special exhibits and more.
