IRONMAN 70.3 Erkner

Get settled with a short warm-up so your first 5–10 minutes feel controlled rather than rushed. When you enter the start area, seed honestly and choose position based on your ability to hold pace through traffic—this race is about efficient forward progress, not getting boxed in. In the first few minutes, prioritize smooth breathing and a calm cadence, keeping your head steady and your line clean to set up a strong, repeatable stroke for the full 1876 m.

You’ll swim 1876 m in freshwater where temperature varies, so start slightly conservative and let your pace build as the body warms. Because the course is longer than a sprint, aim for even effort: smooth technique and minimal lateral deviation will matter more than chasing early speed. If the wind influences surface conditions at the venue, expect chop; keep your stroke compact and focus on staying aligned rather than “powering through” every wave. Fueling during the swim is typically minimal—save your calories and fluids for the bike and run plan, and mentally lock in your first hydration/food action for T1.

In T1, reduce clutter: rack cleanly, lock in your helmet and eyewear before moving, then quickly swap from swim gear to bike setup without lingering. As you mount, focus on smooth cadence immediately—don’t mash power while you settle into speed. The first 5–10 minutes on the bike should feel like “controlled fast,” establishing steady power and consistent breathing before you start tightening your output.

The bike is 88.2 km with only 80 m elevation gain and a flat/fast profile, so it’s built for sustained speed. With wind 5 m/s from the SW, expect headwind/tailwind effects across exposed sections: keep your effort consistent even if speed fluctuates, and avoid spiking power when the wind helps. Your fueling target is 90 g carbs per hour plus 750 mg sodium per hour and about 650 ml fluid per hour—start this routine early rather than waiting until you feel thirsty or “behind.” Aim to take carbs and sodium in small, regular doses, and use the fluid to control intake rhythm; in moderate heat, it’s easier to overshoot later than to catch up after you’ve fallen behind.

In T2, treat the first minutes like a transition drill: get your shoes on fast, then start the run with a short, controlled ramp rather than sprinting out of the chute. The legs will feel heavy when you first come off the bike—focus on quick steps and relaxed shoulders to avoid overstriding. If you’ve fueled correctly on the bike, the transition into the run should feel “worked but available,” not depleted.

You’ll run 21.5 km on a flat/fast profile with 40 m elevation gain—so the main challenge becomes staying controlled as the temptation to run hard builds. With SW wind and moderate heat, you may feel cooler or warmer depending on exposure; use the wind shifts to steady your pace rather than chasing momentary comfort. Your goal is to continue the race-long fueling you started on the bike; if you’re using the standard target, keep carbs and sodium consistent and drink regularly so you don’t fade late. In flat courses, small pacing mistakes compound—settle into a rhythm you can repeat for multiple miles, and keep form efficient (slightly shorter stride, steady cadence) as fatigue rises.
