The Story
You come to Tunis for a 70.3 and you get a 70.3 that feels like Tunis: Carthaginian coast meets French colonial ease. The 1.9km swim sends you into cold river at 14°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 defining leg: 1006m 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 Tunis with 150m 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. The city brings its own dimension: Mediterranean blue, whitewashed Sidi Bou Saïd glimpses, a North African gem on the triathlon circuit. The kind of half-distance race that makes you understand why 70.3 is where triathlon's competitive heart beats loudest.
"The thing about Tunis is the city itself gets into the race. You feel it on the run — the crowd, the setting, the energy. It carries you."
What It Feels Like
70.3 triathlon with Tunis character. This course suits experienced 70.3 athletes who want a course that fights back. This isn't a PB course — it's a character-building one. Five-plus hours of racing through a city this distinctive — the setting adds a dimension no training plan can replicate.
🏊 The Swim
A 1.9km river swim at 14°C. Current adds a variable that changes the race — sometimes helping, sometimes fighting you. Over 1.9km, reading the current correctly can save minutes. Bracing — the kind of cold that sharpens focus. Check the race briefing for swim direction and expected flow conditions.
🚴 The Bike
90km with 1006m 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
A 21.1km rolling run through Tunis with 150m 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 mild 20°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 14°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 1006m 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.
