Race day for this edition — 22 August 2026 — has passed. The guide stays up for reference.
Upcoming race guides →IRONMAN Tallinn is a full-distance 140.6 with five colour-coded bags — blue and red for the bike and run, white for morning clothes, plus orange and black personal-needs bags set out on course. Split transitions: you swim and start the bike at Lake Raku, then rack for the last time at Unibet Arena. Here's exactly what goes in each, when check-in closes, and how the long day runs.
On a split course you never return to where you started, so your kit goes into separate bags that wait for you along the course.
Check the athlete guide for where each bag is dropped and where it waits for you.
This is a split transition over a full 140.6 — the swim and T1 are at Lake Raku south of the city, the bike runs out through Harju County, and T2 and the finish are at Unibet Arena. Add two personal-needs bags out on course and it's five bags to get right before Friday evening.
IRONMAN's colour-to-bag scheme carries the bike and run gear; a 140.6 adds bike and run personal-needs bags. Pack each for the moment it powers and label nothing else.
Tallinn runs a mandatory Friday bike and gear check-in at Lake Raku, with the bike racked overnight — there's no race-morning bike check-in. Athlete check-in opens Wednesday and closes at 17:00 on Friday; bike and gear check-in runs 13:00 to 19:00 that same day.
The 2026 official guide is in. The times below are now confirmed for this edition — a few moved from last year.
Transition 1 opens at 05:30 and closes at 07:30, the age-group swim starts at 07:30, and the street-wear bag drop closes at 08:00. From there it's a long day: the bike course closes at 17:00 and the overall cut-off is 00:30 on Sunday.
Five: blue for the bike, red for the run, white for street wear, plus orange and black personal-needs bags set out on the bike and run courses. Blue stays at Lake Raku; red is at Unibet Arena.
Bike and gear check-in closes at 19:00 on Friday at Lake Raku, and the bike is racked overnight. Athlete check-in closes earlier that day, at 17:00, so do the paperwork before the bike.
They're your personal-needs bags — orange for the bike, black for the run. They're set out at the personal-needs points on course. You won't get them back, so pack a resupply rather than a spare kit, and no valuables.
In the white street-wear bag, handed in at Lake Raku before the drop closes at 08:00. It's transported to Unibet Arena so dry clothes meet you at the finish.
The overall cut-off is 00:30 on Sunday — 17 hours after the final athlete starts. The swim cut-off is 09:50 and the bike course closes at 17:00. Bike and transition bags are collected from 19:00 on Saturday until 01:30 on Sunday.
Lake Raku is on the southern edge of the city and Unibet Arena is out at Rocca al Mare, to the west — two separate venues, not a walk apart. Once you leave T1 you don't return — recce both venues during race week, and plan how your supporters get from the lake to Rocca al Mare.
