The Story

Cartagena, Colombia. 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 mild ocean at 22°C — comfortable — cool on entry, forgotten after 200 metres. 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: 889m 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 Cartagena with 133m 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 70.3 that rewards the athletes who trained specifically for this distance, not just those who scaled down from Ironman.

"People think 70.3 is half an Ironman. Race one in Cartagena and tell me it feels like half of anything."

What It Feels Like

A 70.3 that reflects Cartagena: Caribbean colonial heat. 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 ocean swim in mild saltwater at 22°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 889m 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 Cartagena with 133m 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

→ The bike packs 889m 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.
→ 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.
→ Nutrition is the fourth discipline at 70.3 distance. Practice your race-day fuelling in training until it's automatic. Target 60-80g of carbs per hour on the bike (gels, drink mix, or both), and carry at least one gel for the run. Under-fuelling a 90km bike destroys a half-marathon.
