The Story
Seventy point three miles through Hobart. That's 1.9km in the water, 90km on the bike, and a half-marathon to finish — the world's most popular triathlon distance, in a city that earns the right to host it. The 1.9km swim sends you into cold saltwater at 15°C — bracing — the kind of cold that sharpens focus. It's long enough that a poor start costs real time, short enough that strong swimmers can build a genuine lead. The 90km bike is the centrepiece: rolling with some honest climbs terrain with 423m of climbing that never lets you settle. At 70.3 distance, the bike is where races are won and lost — 90km of rolling road demands constant effort management. A rolling half-marathon through Hobart with 63m of gain. After 90km on the bike, even gentle rises feel significant. Quick cadence on the ups, controlled effort on the downs, and trust the training through the middle kilometres. A half-iron course that doesn't apologise for its difficulty — and neither should you for choosing it.
"People think 70.3 is half an Ironman. Race one in Hobart and tell me it feels like half of anything."
What It Feels Like
A half-iron course in Hobart that suits a broad range of 70.3 athletes — the course is honest enough to challenge veterans and achievable enough for well-prepared first-timers. The city's Tasmanian wilderness on a harbour course extends to the race itself. Recovery is part of the experience: Tasmanian salmon and a Cascade.
🏊 The Swim
A 1.9km ocean swim in cold saltwater at 15°C — long enough that sighting discipline and stroke efficiency matter more than raw speed. Ocean swell can push you off-line; sight every 8-10 strokes. The salt buoyancy helps body position but stings the eyes. Exit through the surf and run to T1.
🚴 The Bike
90km of rolling terrain with 423m of climbing — the course signature. The rises are frequent enough to break any rhythm you try to establish. Over 90km, the cumulative elevation demands constant gear management and power discipline. Don't chase speed on the descents; recover there instead. This bike rewards riders who think in power, not pace.
🏃 The Run
A 21.1km rolling run through Hobart with 63m of gain. The undulations feel disproportionate on legs that have just covered 90km of bike. Keep cadence quick on the ups, use the downs to stretch your stride, and run the tangents. In cold 3°C conditions, each hill amplifies the heat cost. Walk an aid station if you need to — it costs 15 seconds and gains you proper hydration.
💡 Insider Tips
- → Water temperature averages 15°C — that's cold for a 1.9km swim. Train in cold open water regularly in the weeks before. Your first 400m set the tone: if you can settle into rhythm through the cold shock, you'll swim well. A neoprene cap makes a measurable difference.
- → With 423m of elevation over 90km of rolling terrain, the bike is deceptively demanding. The short rises don't look like much individually, but they accumulate. Stay in the aerobars on the flats, spin up the rises, and save your matches for the run.
- → Ocean conditions can shift between recon and race morning. For 1.9km in open ocean, sight every 8-10 strokes — swell can push you hundreds of metres off course without you feeling it. Practice dolphin-diving through shore break and body-surfing back to shore.
