IRONMAN 70.3 Duisburg is a single-transition 70.3 in the Sportpark — you rack once on the Dreieckswiese, with colour-coded bags for the bike and the run, and your bike goes in the night before. The swim is on the regatta course, the finish is on the Klönnewiese, and here's exactly what goes in each bag.
Swim, bike and run all turn through one transition on the Dreieckswiese, beside the regatta course — you come back to the same rack between disciplines. The run winds through the Sportpark and finishes a few hundred metres away on the Klönnewiese, so your dry kit is moved there for you.
IRONMAN's colour-to-bag scheme is the same across European races, so this part is settled. Pack each bag for the discipline it powers — and for changeable mid-August weather in the Ruhr.
Duisburg runs a mandatory day-before bike check-in with the bike racked overnight — there's no race-morning bike check-in to fall back on. You collect your timing chip, wristband and stickers here too, so don't skip it.
The 2026 official guide is in. The times below are now confirmed for this edition — a few moved from last year.
The order is what matters: transition opens at 06:30 and closes at 08:00, your white street-wear bag goes in at the Athlete Garden by 08:30, then the rolling swim start on the regatta course from 08:00.
The blue bag is your bike / T1 bag — helmet, bike shoes, sunglasses, race belt and ride nutrition. It's dropped in transition on the Dreieckswiese at Saturday's bike check-in, the day before.
Yes. Bike check-in is mandatory and day-before, with the bike racked overnight in the Sportpark. There is no race-morning bike check-in, so don't plan to bring it on the day.
Three: blue for the bike, red for the run, white for street wear. It's a single transition, so blue and red both sit at the one rack; the white bag is handed in at the Athlete Garden and moved to the finish for you.
Bike & bag check-in closes Saturday 15 August at 18:00, the day before the race. This is confirmed from the 2026 athlete guide, not last year's provisional time. Have your bike racked and both transition bags dropped before then.
All inside Duisburg's Sportpark: the swim is on the regatta course, you rack once on the Dreieckswiese, and the run finishes on the Klönnewiese a few hundred metres away. You can walk between all three.
Plan for changeable mid-August weather: a light rain gilet for the two flat bike laps if showers are forecast, plus sunscreen for an exposed course. The regatta-course swim is flat and sheltered, so it's the bike and run that set your kit.
Add Duisburg and RackSide turns this into a personal, deadline-aware plan — your wave time against the confirmed 2026 cut-offs and a packing checklist you tick off.
