Chicago River Swim Returns After 98 Years

In a symbolic moment that merges history with renewal, the Chicago River swim has officially returned after a 98-year absence. On September 22, 2025, hundreds of swimmers will dive into the revitalized river for a landmark open-water competition that underscores environmental progress, civic pride, and the city’s renewed connection to its iconic waterway.

A Century in the Making

Once notorious for pollution and deemed unfit for recreation, the Chicago River has experienced a dramatic turnaround over the last two decades. Extensive investment in water quality improvements, infrastructure modernization, and grassroots advocacy have transformed the river into a safe venue for sanctioned swimming.

The event marks not only a sporting milestone but also a powerful symbol of Chicago’s evolving relationship with the natural resources that shape its identity.
