Chain of Rocks Bridge Duathlon
About this race
The Chain of Rocks Bridge has become the permanent home of our Spring Duathlon. Originally held on the historic Eads Bridge we re-located the event to a longer bridge and a more rural bicycle course. Participants will run from Start Line to the Mississippi River and back, followed by a flat, fast out and back bike circuit, returning to a final out and back run leg to the river and back with great views of the mighty Mississippi River. Awesome, right?!
The Chain of Rocks Bridge Duathlon brings an exciting 24.1K to Granite City, Illinois on May 3, 2026. Don't miss this beautiful event!
