Chain Of Rocks Bridge Duathlon
April 23rd 9:00 am - 11:30 am
Entering its sixth year, the Chain of Rocks Bridge is now the permanent home of Big Shark’s Spring Duathlon. Originally held on the historic Eads Bridge, we relocated 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 Illinois to Missouri and back, followed by a flat, fast out and back bike circuit, returning to a final out and back run leg on the bridge with great views of the mighty Mississippi River.
