IRONMAN 70.3 Weymouth is a single-transition 70.3 on the Dorset coast — you rack at one transition at Lodmoor, with two colour-coded bags for the bike and the run, and your bike goes in the night before. The swim is in the bay, the run finishes in town, and here's exactly what goes in each bag.
Swim, bike and run all turn through one transition at Lodmoor — you come back to the same rack between disciplines. The flat seafront run heads into town and finishes at the Pavilion, about a mile from transition, so plan how your dry clothes get there.
IRONMAN's colour-to-bag scheme is the same across European 70.3s, so this part is settled. It's a two-bag race: pack each for the discipline it powers and label nothing else.
Weymouth runs a mandatory day-before bike check-in at Lodmoor 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.
These are last year's times. The 2026 official guide isn't out yet — we'll update them the moment it publishes. Use them to plan the shape of your week; don't lock anything to the minute.
The choreography barely moves year to year — transition opens early, it closes before the gun, then the rolling swim start in Weymouth Bay. The order is what matters.
Two: blue for the bike, red for the run. It's a single-transition 70.3, so both bags sit at the one rack at Lodmoor.
The run finishes at the Pavilion in town, about a mile from transition. There's no tracked street bag, so leave your dry clothes with a supporter at the finish or plan to collect them back at Lodmoor.
Yes. Bike check-in is mandatory and day-before at Lodmoor, racked overnight. There is no race-morning bike check-in, so don't plan to bring it on the day.
Weymouth Bay is sheltered but September-cold — wetsuit territory, and a neoprene cap is worth packing. In rough conditions the swim can be shortened, so watch the morning briefing.
The 90 km loop is rolling and exposed to coastal wind, with some sharp climbs. Pack a rain gilet and clear lenses in the blue bag; it's a tougher, breezier ride than the flat seafront run suggests.
Add Weymouth and RackSide turns this into a personal, deadline-aware plan — your wave time, a packing checklist you tick off, and a nudge the moment the 2026 guide is published so your times stop being provisional.
