A single 70.3 course. IRONMAN typically also offer relay entry at 70.3 events — check the current athlete information for whether it is available in 2027.
Leg 1 of 3
Swim — 1.9km
A 1.2 mile swim in the enclosed Prince of Wales Dock in the SA1 waterfront district — sheltered dock water rather than Swansea Bay, which makes for a considerably more predictable swim than an open-sea start.
- Venue
- Prince of Wales Dock, Swansea
- Elevation gain
- No official figure published — see notes above
- Surface
- Dock — enclosed, still water.
Wetsuit: Determined by water temperature on the day under IRONMAN rules. Dock water in July is usually within the wetsuit-legal range — confirm at the athlete briefing.
Leg 2 of 3
Bike — 90km
A 56 mile undulating loop that leaves the city for Mumbles and then hugs the Gower's coastal clifftops before turning inland through rural Swansea and returning along Swansea Bay into the city. The Gower section is what the race is known for, and it is not flat — the coast road rolls constantly.
- Venue
- Mumbles, the Gower Peninsula and rural Swansea
- Elevation gain
- No official figure published — see notes above
- Surface
- Road — undulating coastal and rural lanes.
Non-drafting
Leg 3 of 3
Run — 21.1km
A 13.1 mile two-lap run from the city centre out past the gold-clad Swansea Arena and along the bay towards Mumbles, before returning to the finish at the Marina. Flat, seafront, and heavily supported.
- Venue
- Swansea city centre, Swansea Arena and the Mumbles road
- Elevation gain
- No official figure published — see notes above
- Surface
- Road and promenade — flat.
Transitions
Transition and the IRONMAN Village are based at Burrows Place in the Maritime Quarter, close to both the dock swim and the Marina finish.

Where IRONMAN 70.3 Swansea starts and finishes
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on. The official course map is the one to use: view it on the organiser's site .
Entry & Ballot
Direct entry summary
Entry is direct through IRONMAN. Pricing for 2027 was not published in the sources checked — IRONMAN 70.3 entry generally sits well above a domestic middle-distance race, so check before committing. Swansea has been confirmed to return in 2027 after the city reported a £4.36m economic benefit from the event.
Ballot policy
No ballot — entry is direct through IRONMAN, first come first served.
Age requirement
IRONMAN 70.3 events normally require athletes to be 18 or over on race day — confirm on the official entry page.
Charity Places
No formal charity-place scheme is published. Athletes commonly fundraise on their own entry.
Race Day Info & Checklist
On the day
- Racing starts from 07:00, with the IRONMAN Village at Burrows Place in the Maritime Quarter.
- The swim is in the enclosed Prince of Wales Dock rather than open sea — a significant advantage over most coastal 70.3s.
- The bike leg closes roads across Mumbles and the Gower, so plan travel around it if you are supporting.
- The run is two laps along the bay, which means spectators see athletes four times from one spot.
- Swansea ranked 11th in the world among IRONMAN 70.3 events in athlete feedback, and the 2027 return follows a reported £4.36m economic benefit to the city.
- IRONMAN reduced the drafting blue-card penalty to 2 minutes league-wide from 2025 (down from the older 5-minute penalty) — expect that to apply here too.
Checklist
- Wetsuit, goggles and the swim cap from your race pack for the dock swim
- Bike, helmet and shoes racked at Burrows Place per the race-morning schedule
- Gearing suited to a genuinely undulating Gower coast road, not a flat 90km
- Run shoes and race nutrition in your T2 bag
- Your timing chip, fitted per the athlete guide
- Sun protection — a July seafront run with two exposed laps
- A meeting point agreed with family and friends at the Marina finish
Transport, Spectating & Where to Stay
Transport
Swansea station is on the Great Western line from London Paddington via Cardiff, around a mile and a half from the Maritime Quarter — walkable, or a short taxi with a bike bag.
Swansea operates Park & Ride sites into the city centre. Check the council's IRONMAN travel page for the race-day arrangements, since the bike course closes roads across Mumbles and Gower.
Extensive closures across Mumbles, the Gower and Swansea Bay for the bike leg, and in the city centre for the run. The council publishes full details ahead of race weekend.
Spectator guide
The Maritime Quarter covers the swim, both transitions and the finish. The two-lap run along the bay means a single spot on the seafront gives four sightings, and Mumbles is the pick of the bike course.
The city-centre and seafront sections are walkable. Reaching the Gower during the bike leg is difficult because those are the closed roads — stay in the city and let the race come to you.
Where to stay
Maritime Quarter / Marina
+ At the IRONMAN Village, transition and the finish — you can walk to everything on race morning. The best base by some distance.
– Limited rooms, and they go early for race weekend.
Swansea city centre
+ The widest choice, close to the station, and on the run course.
– Road closures make driving anywhere on race day difficult.
Mumbles
+ On both the bike and run courses, with the best setting and plenty of places to eat afterwards.
– Cut off by closures during the race, so getting in and out on the day needs planning.
