The Chattanooga 70.3 course
The swim is a 1.4 mile point-to-point downriver swim in the Tennessee River with a rolling start, exiting at Ross's Landing Park. The 56-mile bike heads 11 miles south of town before a 34-mile loop in north Georgia that parallels Lookout Mountain and passes through Chickamauga. The 13.1-mile run is two loops through downtown Chattanooga, the Tennessee Riverwalk, Veterans Bridge and North Shore, finishing at Ross's Landing. The 2026 run detoured off the Walnut Street Bridge because of construction.
Race-day conditions
The official site says the average water temperature is typically in the low 70s F (listed average 72 °F / 22 °C). Wetsuits are permitted up to and including 76.1 °F per the event FAQ.
What to train for
Train at sustained tempo effort on the bike and practice running off the bike in weekly bricks. Rehearse fueling and pacing at goal intensity so the half marathon is run, not survived. The rolling bike course rewards steady power on repeated short climbs rather than surges.
