The 116-mile IRONMAN Chattanooga bike course is legendary, making this IRONMAN the longest course in the world. Athletes will ride 11 miles south of town before beginning two 47-mile loops in north Georgia. The additional 4 miles will be sure to give you an additional badge of honor on race day and prove more than worth it thanks to the incredible views as you parallel Lookout Mountain on this rolling course with great road surfaces. As athletes near the end of the loop, they will get the opportunity to ride through historic Chickamauga.
