What to pack for IRONMAN 70.3 Cascais
Cascais 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 night before. Here's exactly what goes in each, when check-in closes, and how race morning runs.
70.3Split transitionCascais, PortugalSun 4 Oct 2026
ⓘThe layout, bags and check-in shape come from the race calendar and don't change year to year. Exact times are carried from the 2025 athlete guide and marked provisional until the 2026guide drops — we never show last year's deadline as this year's fact.
A split transition, in three places.
Swim and bike start at the marina. The bike comes back to a different transition by the park, and the run finishes in town — you never return to where you started. That's why your kit is split across bags that get moved for you while you race.

▪Because it's a point-to-point split, anything you want after the swim has to already be in the right bag at the right venue — there's no nipping back to a single transition spot. Pack to the bag, not to the moment.
Three bags, by colour.
IRONMAN's colour-to-bag scheme is the same across European 70.3s, so this part is settled. Pack each bag for the discipline it powers and label nothing else.

Dropped at T2 the day before. It's waiting for you off the bike.
White bagMorning clothes — start → finish
- Warm dry layer

- Small towel

Handed in at the swim start; moved to the finish so dry clothes meet you there.
+What you carry to the water (not in a bag): wetsuit, goggles, timing chip on the ankle, and the swim cap from your race pack. Everything else has already gone into the three bags above.
Your bike goes in the night before.
Cascais 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. The shape of that is fixed; the exact closing minute is this edition's detail.

This is last year's closing time. The 2026official guide isn't out yet — we'll update it the moment it publishes, and only then does it become a hard, this-year deadline. Use it to plan the shape of your Saturday; don't lock it to the minute.
How the morning typically runs.
The choreography barely moves year to year — transition opens early, morning-clothes bag goes in, T1 closes, then the rolling swim start. Times below are from the 2025 guide and provisional; the order is what matters for now.

Cascais, answered.
What colour bag is the bike bag at Cascais?
The blue bag is your bike / T1 bag — helmet, bike shoes, sunglasses, race belt and ride nutrition. It's racked with your bike at the marina the day before.
Do I have to check my bike in the day before?
Yes. Bike check-in is mandatory and day-before, with the bike racked overnight at Marina de Cascais. There is no race-morning bike check-in, so don't plan to bring it on the day.
Can I pack or sort kit on race morning?
Only your white morning-clothes bag is handled on the day. Blue and red are dropped on Saturday and you can't get back into them — everything for the bike and run has to be right before check-in closes.
What time does check-in close?
Last year it closed around 17:30–18:00 on Saturday. We hold this as provisional until the 2026 athlete guide is published, then confirm the exact minute — we won't show last year's time as this year's deadline.
Why are there three bags?
Cascais is a split (point-to-point) transition: swim and bike start at the marina, the run starts from a second transition by the park, and you finish in town. The colour-coded bags carry your kit between those points so you don't have to.
What about the white bag — where does it go?
The white bag holds the dry clothes you arrive in. You hand it in at the swim start and it's moved to the finish, so warm kit is waiting when you cross the line.
