Support the Warriors

Opportunity Knocks is an Illinois 501c.3 non-profit organization that serves young people who have intellectual and developmental disabilities (I/DD) through social, recreational and life-skills programming.

The people we serve are Warriors and it is our belief that their place in the community is both valuable and necessary. We envision a community where individuals with developmental disabilities have an active and supported presence.

Our socially interactive programming places consistent emphasis on the value of self-advocacy and community integration. The goal is to provide opportunities for self-enrichment in the life of the Warrior, in turn giving the Warrior an opportunity to enrich the community.



We will run in the rain if you will!! If there is severe weather (thunder/lightning/heavy downpour) at 5PM or later – the Walk to Run Club will be canceled that evening!


The Bank of America Chicago Marathon start line is located in Grant Park at the intersection of Columbus Drive and Monroe Street.
