Chain of Rocks Bridge Duathlon
The Chain of Rocks Bridge Duathlon is a multisport event located in Granite City, Illinois. The race utilizes the historic bridge over the Mississippi River and the surrounding rural landscape for its course. Participants can enter as individuals or as part of a relay team.
The event features a split format with the following segments:
- 1.5 mile run
- 12 mile bicycle ride
- 1.5 mile run
The opening run leg takes participants from the starting line toward the Mississippi River and back. The transition leads into a bicycle circuit described as a flat, fast out and back route through rural areas. The final segment consists of another run leg that returns toward the river, providing views of the water before heading back to the finish area.
The registration period opens in late October and concludes at the beginning of January. The total distance covered across all three segments is approximately 15 miles. Visit the organization's website for the most recent information.
