The Story
Seventy point three miles through Galveston. 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 cool saltwater at 18°C — cool enough to want a wetsuit, warm enough to swim without panic. 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 defining leg: 1116m of elevation gain across a mountainous course that separates those who trained for this specific distance from those who just showed up fit. Ninety kilometres of climbing changes the race equation entirely. A rolling half-marathon through Galveston with 167m 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. That's the deal, and it's a good one.
"People think 70.3 is half an Ironman. Race one in Galveston and tell me it feels like half of anything."
What It Feels Like
A half-iron course in Galveston that suits experienced 70.3 athletes who want a course that fights back. This isn't a PB course — it's a character-building one. The city's Gulf Coast grit on a barrier-island course extends to the race itself. Recovery is part of the experience: shrimp po'boy and a Shiner Bock.
🏊 The Swim
A 1.9km ocean swim in cool saltwater at 18°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 with 1116m of climbing — a mountainous bike course that makes the 90km the race's decisive leg. Power-to-weight matters more than pure wattage. The climbs test your legs; the descents test your nerve. Come with a compact crankset, climbing legs, and the discipline to save something for 21.1km of running.
🏃 The Run
21.1km of rolling Galveston terrain. After the bike, each rise lands differently than it would on fresh legs. The rollers add a psychological dimension — the finish always feels further than the markers suggest. Quick turnover, short stride on the climbs, and trust your fuelling from the bike.
💡 Insider Tips
- → At 18°C, the water is cool enough to tighten your breathing on entry. Practice cold-water starts in training — jump in and swim 200m hard, then settle. The 1.9km swim is long enough that early panic costs minutes, not seconds.
- → Average temperatures around 24°C mean the run will feel hotter than the number suggests — you'll have been racing for 3+ hours by then. Front-load your hydration on the 90km bike. By the time you're thirsty on the run, you're already in deficit.
- → Humidity averages 77% — sweat won't evaporate, so your body's cooling system works at half capacity. Reduce your bike power and run pace by 5-10% from your temperate-weather targets. Ice at every aid station. This is a 70.3 where smart athletes beat fit athletes.
