The event benefits the mission to grant the wishes of children with life-threatening medical conditions.
Participants enriching lives with hope, and some happiness, too, one stride at a time -- even in the pouring rain.
"I think it's a great organization and the only reason why I'm here today is because I think it's a great cause," said runner Steve Radev.
They came dressed up and ready to walk and run, all to benefit the Make-A-Wish Illinois.
To help kick things off on a Bears Sunday was former Chicago Bear Desmond Clark.
"The way I'm trying to make an impact is by running 5Ks and raising money for Wish Kids to go on their Wish Trips," Clark said. "I have a race every month trying to get these guys to run with me and help fundraiser."
Supporters, families, and even Make-A-Wish children were there to take part.
Wish kid 11-year-old Ashanti Norlas was the Grand Marshal. She put the whole event into perspective. You'd never know she's suffered through multiple life-threatening medical illnesses. Those conditions took both her hands, and her legs, but she was all smiles Sunday, and she has big plans for her future:
"Someday when I get older I might make some money and save it up for charity, for hospitals and poor people," she said.
People were encouraged to wear costumes of their favorite characters and superheroes.
Although the true superheroes are kids like Ashanti, proving to all endurance and hope can make any wish come true.
