Also this weekend

Melbourne is a standalone 70.3 rather than a festival — the day is the half-distance race and its relay and aquabike categories.

Leg 1 of 3

Swim — 1.9km

A new course for 2026, starting with a rolling start in front of the St Kilda Sea Baths. Athletes swim 100m west, turn left south towards St Kilda Marina, then right and west, then right and north under the new St Kilda Pier, before a final right into the swim finish chute directly in front of Catani Gardens — the shortest possible run into transition. The change also means spectators can watch the whole swim from the pier.

Venue

Surface
Sheltered bay.

Wetsuit: Port Phillip Bay averages around 18°C at this time of year, which the organiser expects to make it a wetsuit-optional swim. Confirmed on the day against the measured temperature.

Leg 2 of 3

Bike — 90km

Two clockwise laps of Beach Road — the road every cyclist in Melbourne already trains on. From T1 the course heads briefly north, then south along the coast past Half Moon Bay and the southern point of Beaumaris, turning just before the Mordialloc Life Saving Club and returning to St Kilda for the second lap. Fast, flat and, by the organiser’s own description, some of the best riding Melbourne has.

Non-drafting

Leg 3 of 3

Run — 21.1km

Two clockwise laps along the St Kilda and Elwood waterfront, out south on Pier Road onto the Bay Trail, the length of St Kilda Beach to a turnaround just past Elwood Beach, and back north to Catani Gardens. The second lap finishes down the palm-lined avenue at Catani Gardens, with the Melbourne CBD skyline across the water the whole way.

Wetsuit outlook

Will you need a wetsuit at IRONMAN 70.3 Melbourne?

Water temperature at open sea in November has typically been 16.7°C, ranging from 15.6°C to 18°C in eight of every ten years. Against IRONMAN / 70.3's thresholds for this race's 1900m swim, that means:

Wetsuit optional — and recommended

Up to and including 24.5°C (76.1°F) every athlete may wear a wetsuit and remain eligible for awards.

What would have happened in each of the last 16 years

  • Wetsuit mandatory4 of 16
  • Optional (recommended)12 of 16

What the organiser says

Port Phillip Bay averages around 18°C at this time of year, which the organiser expects to make it a wetsuit-optional swim. Confirmed on the day against the measured temperature.

Calibrated against measured sea-surface data, to within about 1°C. The official temperature is taken an hour before the start, and only that reading decides the rule on the day.

Transitions

Transition sits at Catani Gardens, with the new swim finish chute directly in front of it. The bike dismount line is 100m from transition on the opposite side to the swim exit, with entry on the western side; toilets and a small water station are inside, and the run exit is on the south-east.

Where IRONMAN 70.3 Melbourne starts and finishes

Race Day Info & Checklist

On the day

  • The swim course was rebuilt for 2026, moving the finish chute directly in front of Catani Gardens and opening St Kilda Pier as a spectator vantage point.
  • The bike is two laps of Beach Road, which is closed for the race — the one day a year Melbourne’s busiest training road belongs to the field.
  • The whole course sits within a few kilometres of the Melbourne CBD, which makes it one of the easiest 70.3 races anywhere to reach and to spectate.
  • Water in Port Phillip Bay averages around 18°C in November — cool enough that most people will want a wetsuit even where it is optional.
  • On-course fuel is typically PURE Sports Nutrition Electrolyte and Maurten Energy Gels/Bars, the nutrition partners confirmed in official Athlete Information Guides for other Australian IRONMAN races — not independently confirmed for this specific event.

Checklist

  • A wetsuit, even though the swim is likely to be wetsuit-optional at around 18°C
  • A bike plan for a genuinely flat two-lap course, where the temptation is to ride too hard early
  • Sun protection for a flat, unshaded two-lap run along the bay
  • Gear bags packed to the published transition process
  • A tram plan — the 96 runs from the CBD to the door
How many weeks do you actually need to train for Middle Distance (70.3)?

Transport, Spectating & Where to Stay

Transport

The 96 tram runs from Southern Cross and the CBD to St Kilda beach, and Balaclava station is a short walk. This is one of the most public-transport-accessible 70.3 races in the world.

Not published for this event — check the official race website.

Beach Road is closed from St Kilda to Mordialloc, along with the St Kilda foreshore roads.

Spectator guide

St Kilda Pier for the whole swim — new for 2026 — Catani Gardens for both transitions and the finish, and anywhere on the Bay Trail for the run.

You do not need to move. The swim, both transitions, the run and the finish are all within a few hundred metres of Catani Gardens.

Where to stay

St Kilda

+ Walk to everything. Plenty of accommodation, and the beach and Acland Street on the doorstep.

St Kilda on a Saturday night is not quiet.

Melbourne CBD and Southbank

+ The widest choice, with a direct tram to the start.

A tram ride on race morning, before the trams are frequent.

Elwood and Brighton

+ Quieter, on the run and bike course, and a genuinely pleasant part of Melbourne.

Further from the event village and its logistics.
