About: 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. The iconic Chain of Rocks Bridge and surrounding area is the perfect venue to ease into an active event season. The event starts and finishes at the foot of the Chain of Rocks Bridge on the Illinois side. 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?!
