Course
The Augusta 70.3 course
The 1.2-mile swim is a point-to-point downriver swim in the Savannah River, starting on the South Carolina side by SRP Park, the minor league ballpark, and finishing under the 5th Street Bridge. The 56-mile bike is a single loop from the transition area in downtown Augusta into the Georgia backcountry, with rolling hills, several long climbs, a few technical turns and long straightaways where you can settle into aero.

The 13.1-mile run starts on the Augusta Riverwalk, crosses the 13th Street Bridge to the North Augusta Greeneway trail and returns along the Savannah River to finish in historic downtown Augusta. More than 9 miles of the run are shaded, with only minor elevation gain on gentle rollers.

- Race-day conditions
- IRONMAN lists typical race-day air temperatures of about 66 °F at dawn rising to 76 °F, with highs of 72 to 79 °F in 2023–2025, and late-September mornings are usually humid. The river averages about 74 °F and reached 76 °F in 2025, right at the 76.1 °F wetsuit cutoff, so be ready to swim with or without one. Even with the shaded run, plan fluids and electrolytes for the humidity.
What to train for
The downriver current makes the swim quick, so the bike is where your day is built: practice holding steady power on long gradual climbs and staying smooth through technical turns.
Ride rolling routes of 2.5 to 3.5 hours with sustained efforts at half-iron power, and finish many of them with a 20 to 30 minute run off the bike.
On the run, keep the first 3 miles relaxed and save something for the bridge crossings. Do some swims without a wetsuit in case the water is too warm.

Taper
Tapering for the Augusta 70.3
Start the taper ten to fourteen days 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.
