Build your IRONMAN Chattanooga plan
The instant browser builder only plans running races, so a full-distance (140.6) triathlon plan comes from the coach itself. It opens with the IRONMAN Chattanooga already filled in (estimated for September until the date is announced), asks about your week and your current fitness, and writes every session. Free account (or start as a guest), no card. You are about 51 weeks out.

The IRONMAN Chattanooga course
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. The 26.2-mile run covers two loops through downtown Chattanooga, the Tennessee Riverwalk, Veterans Bridge and North Shore, finishing at Ross's Landing.
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 durability 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.
