The Story

Gothenburg, Sweden. A 70.3 that doesn't trade on brand name alone — it trades on a course that demands specific preparation and rewards athletes who respect the distance. The 1.9km swim sends you into frigid flowing river at 12°C — cold enough to steal your breath on entry. 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: 1191m 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 Gothenburg with 178m 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. Humidity sits around 78% — over five hours, the cumulative effect of impaired cooling changes the race. No shortcuts, no easy legs, no forgiveness for a bad plan.

"The swim wakes you up, the bike breaks you down, and the half-marathon shows you who you really are. That's 70.3 in Gothenburg."

What It Feels Like

A 70.3 that reflects Gothenburg: west-coast Swedish ease. It suits experienced 70.3 athletes who want a course that fights back. This isn't a PB course — it's a character-building one. Race it once and you'll understand why 70.3 is the distance athletes come back to, year after year.

🏊 The Swim

A 1.9km river swim at 12°C. Current adds a variable that changes the race — sometimes helping, sometimes fighting you. Over 1.9km, reading the current correctly can save minutes. Cold enough to steal your breath on entry. Check the race briefing for swim direction and expected flow conditions.

🚴 The Bike

90km with 1191m 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 Gothenburg 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

→ Water temperature averages 12°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.
→ The bike packs 1191m of climbing over 90km — that's a real day in the saddle. Keep cadence above 80rpm on the climbs and resist the urge to hammer. Every watt you spend above threshold on the bike comes out of your half-marathon. A compact crankset with a 28+ cassette is non-negotiable.
→ River swims can have current — over 1.9km this matters more than in shorter distances. Check the race briefing for swim direction and expected flow. Position yourself to use the current where possible, and ferry-glide at an angle across any cross-current rather than fighting it head-on.
