IRONMAN 70.3 Augusta blazes the trail for speed, excitement, and tradition as athletes traverse through the Savannah River, the scenic Georgia backcountry, and the heart of downtown. Athletes will take on a quick 1.2-mile down-river swim in the Savannah River before biking 56-miles through rural Augusta and a flat 13.1-mile spectator-filled run course along the North Augusta Greeneway trail.
