IRONMAN 70.3 Rio de Janeiro is a split-transition 70.3 — so you don't pack one bag, you pack three colour-coded ones that travel for you, and your bike goes in the day before. The swim is off Copacabana Beach, the run finishes across town at Marina da Glória, and here's exactly what goes in each bag, when check-in closes, and how race morning runs.
On a split course you never return to where you started, so your kit is split across colour-coded bags that get moved for you while you race.
Swim and bike start under the Copacabana Fort. The bike comes back to a different transition at Marina da Glória, and the run finishes there too — you never return to where you started. That's why your kit is split across bags that get moved for you while you race.
IRONMAN's colour-to-bag scheme is the standard one — blue for the bike, red for the run, white for morning clothes. Pack each bag for the discipline it powers and label nothing else. One Rio-specific rule: your wetsuit and everything you swam in go into the blue bag after the swim.
Rio runs a mandatory day-before bike and bags check-in with the bike racked overnight — bikes are not permitted into transition on race morning, so there's no race-morning check-in to fall back on. You collect your timing chip on your way out of bike check-in.
The 2026 official guide is in. The times below are now confirmed for this edition — a few moved from last year.
The choreography is confirmed for 2026: transition at Copacabana Fort opens at 05:00 and closes at 06:25, you bring your white bag in and leave it by your bike, then the swim starts — pros at 06:30, age-group rolling start from 06:45.
The blue bag is your bike / T1 bag — helmet, bike shoes, sunglasses, race belt and ride nutrition. It's racked with your bike at Copacabana Fort the day before, and after the swim your wetsuit and swim kit go back into it.
No, and this is the Rio quirk: it's a split race. Your blue bag and bike stay at Copacabana Fort (T1), your red run bag is dropped at Marina da Glória (T2), and your white morning bag starts at T1 and is moved to the finish for you.
Yes. Bike and bags check-in is mandatory and day-before, with the bike racked overnight at Copacabana Fort. Bikes are not permitted into transition on race morning, so there is no race-morning bike check-in.
Bike and bag check-in closes Saturday 8 August at 18:30. This is confirmed from the 2026 athlete guide, not last year's provisional time — plan your check-in window (they're allocated by bib number) to have both your bike and red bag in before then.
The swim is an ocean swim off Copacabana Beach, which can be choppy with Atlantic swell. August is Rio's winter, so water is typically cool enough to be wetsuit-legal — wetsuits are permitted up to 24.5 °C for age-groupers. Check the race-morning water-temperature call before you zip up.
August is the southern-hemisphere winter — mild and mostly dry, warm by day but cool at the pre-dawn start. Pack arm warmers or a throwaway top for the early swim start in the white bag, and sunscreen and a cap for a run that can still get sunny by early afternoon.
Add Rio de Janeiro 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.
