The 2.4-mile swim is point-to-point in the Tennessee River, starting from a dock 2.4 miles upstream of transition and exiting at Ross's Landing Park, mostly with the current. The 112-mile bike runs north on US-27 through Red Bank to Soddy Daisy for three loops with a dedicated lane, paralleling the Cumberland Plateau.

- Race-day conditions
- The course page says water temperatures in the mid 70s F make wetsuits a race-time decision, so athletes should be prepared for both (listed average 76 °F / 24 °C).
What to train for
Build aerobic endurance across all three sports and practice race-day fueling in long bricks, since nutrition often decides the second half of the marathon.
Rehearse pacing so the bike effort leaves enough in reserve for a steady run.
Prepare for a possible non-wetsuit swim and for warm late-summer conditions on the run.

Your build to race day
Taper
Tapering for the IRONMAN Chattanooga
Start the taper two to three weeks before race day. Trim the volume in all three sports, keep short race-pace efforts in each, and do one last short brick so running off the bike still feels familiar. The course rolls, so keep one short session on undulating ground in the first taper week. With the race on September 26, 2027, your taper starts around September 8, 2027.
