IRONMAN Leeds is a single-transition full 140.6 — you rack once at Roundhay Park, with a blue bag for the bike and a red bag for the run, a white bag for street wear, and optional bike and run personal-needs bags handed out on course. The swim is two loops of Waterloo Lake and your bike goes in the day before. Here's exactly what goes in each, when check-in closes, and how the long day runs.
Swim, bike and run all turn through one transition at Roundhay Park — you come back to the same rack between disciplines, and the run finishes inside the park. It's a single transition, but a full 140.6 adds bike and run personal-needs bags handed to you out on the course.
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. On a full there are also personal-needs bags for the bike and run — mid-course aid you hand in on race morning and collect at the marked points out on course.
Leeds runs a mandatory day-before bike & bag check-in at Roundhay Park with the bike racked overnight — there's no race-morning bike check-in to fall back on. Check-in closes Saturday at 16:30, confirmed from the 2026 athlete guide.
The 2026 official guide is in. The times below are now confirmed for this edition — a few moved from last year.
Transition opens 04:30 and closes 06:00, the white bag and personal-needs bags are dropped in that window, then the age-group rolling swim start gets underway from 06:00 — confirmed from the 2026 athlete guide. It's a full day: the course stays open past 23:00.
The blue bag is your bike / T1 bag — helmet, bike shoes, sunglasses, race belt and ride nutrition. It hangs at your rack at Roundhay Park the day before, and your wetsuit, cap and goggles go into it after the swim.
Three colour-coded gear bags — blue (bike), red (run) and white (street wear) — plus optional bike and run personal-needs bags handed out on course. The blue and red bags hang at your single rack; the white bag goes to the finish and the personal-needs bags are set out at the marked stations.
Yes. Bike & bag check-in is mandatory and day-before, racked overnight at Roundhay Park, closing Saturday at 16:30. There's no race-morning bike check-in, so don't plan to bring it on the day.
The mandatory bike & bag check-in closes Saturday at 16:30, 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 sorted before then.
On a full you can. Bike and run personal-needs bags hold mid-course aid — extra nutrition, a spare tube, salt — that you drop on the way to swim start and reach at the marked personal-needs points (bike around 90.7 miles, run partway round the laps). They're optional and not returned, so don't put anything valuable in them.
It's a 17-hour day. The swim closes 2:20 after your individual start, the bike 10:30 after (with intermediate cut-offs at 73 and 90.7 miles), and the run 17:00 after — confirmed from the 2026 athlete guide. The hilly three-lap bike, with over 2,500 m of climbing, is the part to respect.
Add Leeds 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.
