About Chain of Rocks Bridge Duathlon

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?!
