- Walk & Roll is the oldest American Cancer Society event in Illinois, celebrating 46 years in Chicago on Saturday, April 22, 2017 at Solider Field. Participants choose to walk or run 5K, skate 10K, or bike 15K along Chicago's Lakefront to raise funds and awareness for all cancers. Walk & Roll honors cancer survivors and caregivers, guests are treated to family-friends activities and are encouraged to picnic in the park after!
