Race Day at Melbourne 70.3: Timeline, Common Mistakes and Plan B

The days before

Get to Melbourne with a buffer: 3-4 days if you're coming from far away. Race week has three priorities. First: registration and the briefing, following the official event schedule, as the organisers themselves recommend in their race day tips. Second: recon. A bike ride on a stretch of Beach Road to feel the road surface and the wind, an easy run on the Bay Trail, and above all a swim at St Kilda Beach: the water averages around 18 °C and getting in at dawn is a small shock if you've never tried it. Third: bike check-in according to the times in the official program, which you should verify in the athlete guide because the info sheet doesn't list the times.

The morning: cold first, race later

Early November in Melbourne means lows around 11 °C. The start is at dawn: between wake-up, transition and waiting for the start, you'll spend a couple of hours in the cold. Bring warm layers to leave in transition or old clothes to toss before getting in the water. The swim start is rolling: all cut-off times run from your individual start, not from the gun. Memorise them: swim 1h10, bike 5h30, finish 8h30.

A typical timeline

• Wake up 3 hours before your estimated start, tried-and-tested breakfast, no experiments.
• Transition: pump the tyres, check gearing and on-bike nutrition, visualise the swim-in and bike-out flow.
• Wetsuit on without rushing, short warm-up, enter the rolling start based on your declared swim time.
• In the water: the bay is typically more manageable than open ocean, but the day's conditions call the shots.

The common mistakes

1. Dressing in race kit at 5 a.m.: you freeze in the start corral and start tight. Throwaway layers, always. 2. Getting carried away on the tailwind section of the bike: the bill comes due at the turnaround. Steady watts from the first km. 3. Never having tested your wetsuit in open water: at 18 °C you'll almost certainly wear one. 4. Ignoring the forecast until the night before: here the weather can change in a few hours, with rain roughly one day in three this time of year. 5. Starting the run at dream pace: the dead-flat course tempts you to overdo it in the first 3 km.

Plan B: be ready for a modified race

This isn't theoretical: in 2023 the swim was shortened due to conditions, and several 2025 race reports describe a cancelled swim because of bad weather, with wind and rain all day. That means two things. First: you need an alternative format in your head (duathlon or shortened swim) without your motivation collapsing; the race still counts. Second: your gear plan must cover the extremes, from sunshine around 23 °C to cold rain with gusts. The night before, decide on two complete setups, from wheel choice to clothing in T1, and choose in the morning based on the actual sky, not on hope.

What to do now

• Write your race-day timeline backwards, from the start to your alarm, with real times.
• Prepare a dual-scenario gear checklist: good day and bad day.
• Plan at least two wetsuit swims in cool water before flying to Australia.
• Simulate a dawn start in training: early alarm, race breakfast, quality session done by 8 a.m.
• Watch the official briefing when it's published and note the rules on the rolling start and cut-offs: they're calculated from your chip, not from the first athlete in the water.
