IRONMAN 70.3 Augusta
Sunday, 27 September 2026
IRONMAN 70.3 Augusta blends a ~1.9 km freshwater swim with a rolling 89.8 km bike (456 m gain) and a rolling 21.1 km run (91 m gain) where hot conditions and an easterly wind mean hydration and pacing are everything.

Worlds qualification — slots TBAsee who qualified →Arrive with a repeatable pre-start routine: 8–12 minutes easy aerobic movement plus a few short accelerations so your body is awake before the first horn. Seed for your realistic swim time—getting clear water early reduces early-date pushing and wasted energy. On the first minutes, focus on calm breathing and smooth pressure; avoid sprinting away from the crowd and let your rhythm settle into long, efficient strokes.
You’ll cover 1931 m in freshwater where temperature varies, so plan around “warmer-than-cold” comfort if it’s humid and hot. The key is to start controlled: aim for steady effort until you find feet or clear space, then gradually build stroke efficiency rather than speed. With hot air temperatures on deck, keep your breathing relaxed and don’t overcook the first buoy turn—saving energy helps you exit ready for the bike. Fuel-wise, you typically won’t take much during the swim; make your post-swim transition plan and the first bike drinks timing the priority.
Finish the swim composed—strong but not frantic—so you can transition quickly and start the bike with your breathing and cadence stable.
Transition 1 should be efficient: dry off quickly where needed, put on helmet and glasses, and confirm your bike computer/gear selection before you fully commit. The first 5–10 minutes off the swim are about establishing control—smooth power, watch your heart rate, and get your fueling mechanism running early so you don’t play catch-up later. Because this course is rolling, set expectations mentally: you’ll feel frequent changes, so don’t chase power on every rise—stay patient over the undulations.
The bike is 89.8 km with 456 m of rolling elevation, so expect repeated up-and-down efforts rather than one sustained climb. With hot conditions and an easterly wind (4.4 m/s from the E), you’ll likely feel wind effect more as you change direction and as exposed sections open up—use it to regulate effort instead of forcing speed. Your fueling target is 90 g carbs per hour with 1000 mg sodium and 800 ml fluid per hour, and you’ll want to start early enough that you’re hitting the rate consistently rather than late in the ride. Drink consistently even if you don’t feel thirsty; with heat and wind, sweat loss and electrolyte needs can rise faster than you think. Keep nutrition accessible and predictable: take carbs/sodium with your planned bottle schedule, and aim for steady power on the rollers so your run legs aren’t compromised.
The best bike finish is “controlled steady”: hit your carbs/sodium/fluid rate, stay patient on the rolls, and let the wind shape effort rather than dictate it.
In T2, treat the first steps like a restart: get your shoes locked in, take a few seconds to stand tall, and begin the run with slightly reduced intensity so your legs transition from spinning to loading. Your biggest cue off the bike is to keep cadence from collapsing—rolling terrain plus heat can tempt you to overstride. Focus on smooth, even breathing immediately; the first 1–3 km sets the tone for how well you can hold pace.
The run is 21.1 km with 91 m of rolling elevation, which means frequent mild changes rather than steep climbs, but the heat makes those “small hills” feel bigger. With hot conditions, your pacing should prioritize staying in a manageable effort zone; if you start too fast, the rolling profile will amplify fatigue later. Use your fueling plan from the bike as your baseline: continue taking in carbs and fluids consistently so you don’t fade as temperature rises. With wind from the E at 4.4 m/s, you may feel cooling help during certain exposed segments—don’t let that illusion push your pace; instead, use it as a pacing regulator while maintaining your nutrition rhythm. Over the rolling course, keep steps efficient—shorter stride uphill, quick and controlled cadence downhill—to preserve energy for the final stretch.
Stay disciplined on effort and cadence early; consistent hydration/carbs through the middle of the run is what protects your finish.
Build your race plan around hot conditions: start controlled, begin fueling early on the bike, and keep drinking consistently through the run to match your targets (90 g carbs/hr, 1000 mg sodium/hr, 800 ml fluid/hr).
