Quick Facts
Getting There
St. Kilda is easily accessible via public transport from Melbourne CBD, with multiple tram routes servicing the beachfront area. If driving, expect limited parking on race day due to road closures - arrive early and consider parking in surrounding suburbs. Public transport is highly recommended, with special early services typically operating for athletes. Transition areas generally open 2-3 hours before race start, allowing ample time for bike setup and pre-race preparation.
Weather & What to Pack
Early November in Melbourne brings pleasant spring conditions, with temperatures typically ranging from 12-22°C. Morning starts can be cool, with the swim portion requiring wetsuits in Port Phillip Bay waters (usually 14-17°C). Expect variable conditions throughout the day as temperatures rise during the bike and run legs. Melbourne's notorious weather variability means being prepared for sun, wind, or occasional showers. Strong sun protection is essential, along with consistent hydration strategies for the warmer afternoon temperatures during the run portion.
