IRONMAN 70.3 Poznan
Sunday, 30 August 2026
IRONMAN 70.3 Poznan is a fast, mostly flat day—1934 m in freshwater, a 90.8 km flat/fast bike, then a 21.2 km flat run—where disciplined fueling in moderate air and a steady W wind will decide your pace.

Worlds qualification — slots TBAsee who qualified →Arrive early enough to find your start group based on your realistic swim time. Do a short, purposeful warm-up in the water if available, then spend the last few minutes settling your rhythm (smooth breathing, consistent kick) rather than going hard. From the start, get comfortable quickly: find clear water, establish your line, and keep the first 200–400 m controlled so you don’t overcook your arms before the course opens up.
You’ll swim 1934 m in freshwater, where temperature can vary, so prioritize steady effort over intensity. With open-water drafting dynamics, aim to swim your own efficient path—don’t chase every surge—especially when traffic thickens. Expect turns and navigation to matter: keep your sighting frequent enough to stay aligned without over-rotating. Fueling during the swim is not the focus; instead, be ready to transition efficiently and start your bike fueling on time.
Finish the swim composed—strong but not sprinting—so your legs and breathing stay under control for the bike start.
Think “transitions first”: as you come out of the water, get calm and spend a few seconds checking your kit—shoes on, helmet secured, any pre-bike drink within reach, and everything where you want it. During T1, keep it efficient: hydrate, rack smart, and remount quickly without rushing your setup. In the first minutes of the bike, build gradually—settle into a steady cadence and breathing before you lock in your target power/speed.
The bike is 90.8 km with about 163 m of total elevation—flat/fast—so it’s built for consistent, efficient output rather than big surges. With wind around 4.5 m/s from the W, expect a noticeable cross/head component at times; keep your aero position stable and make smooth steering corrections so you don’t lose power fighting the bike. Fuel and drink to the planned rate: target 90 g carbs per hour, 750 mg sodium per hour, and 650 ml fluid per hour, taking it consistently rather than waiting for thirst. On a flat course, it’s easy to ride too “hot” early—stay disciplined, then keep the rhythm strong through the middle and late sections so the run comes out feeling controlled.
Your key bike job is staying steady in the wind and hitting the full fueling plan—this is what protects your 21.2 km run.
In T2, get your legs organized immediately: take a few smooth strides to settle your cadence and keep your breathing calm for the first kilometer. Don’t force pace off the bike; let the flat/fast profile help you gradually find speed while you convert the bike work into consistent running mechanics. Take a moment to secure nutrition access and be ready to drink as soon as you’re moving comfortably.
You’ll run 21.2 km with only about 25 m elevation gain—flat/fast—so the temptation is to sprint early. Moderate heat (air temperatures roughly 14.4–23.5 C) means you should watch both breathing and thirst; if you feel yourself overheating, slightly shorten your stride and stay smooth rather than pushing harder. Continue your planned hydration and carb intake so you don’t get behind—consistent fueling is critical because the course won’t “save you” with elevation-driven pacing. With steady conditions, aim for even effort: gradually improve your rhythm as the miles settle in, and keep your focus on controlled posture and quick turnover through the latter stages.
The run will feel “easy on paper”—stay patient early, then execute steady fueling to keep form and pace to the finish.
