The Story

You come to Cancun for a 70.3 and you get a 70.3 that feels like Cancun: Caribbean turquoise on a resort-zone course. The 1.9km swim sends you into mild open 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: 907m 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. The 21.1km run rolls through Cancun, adding 136m of climbing to legs already tested by the bike. The undulations are psychological as much as physical — each rise feels larger than it is when you've been racing for four hours. A half-iron course that doesn't apologise for its difficulty — and neither should you for choosing it.

"The bike in Cancun is where the race happens. Ninety kilometres of honest road — you can't fake fitness over that distance."

What It Feels Like

A 70.3 that reflects Cancun: Caribbean turquoise on a resort-zone course. 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 907m 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 Cancun 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

→ Expect race-day temperatures around 28°C. For a 70.3, heat management is race management. Pre-cool before the start, ice in your tri suit at T2, and pour water at every aid station on the half-marathon. Sodium-load the day before. Drop your run target pace by 10-15 sec/km in these conditions — the athletes who respect the heat finish fastest.
→ The bike packs 907m 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.
