The Story

The half-iron distance asks a particular question: can you hold race pace for five-plus hours across three disciplines? In Lima, the course adds its own follow-up questions. The 1.9km swim sends you into mild saltwater 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: 867m 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 Lima, adding 130m 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. No shortcuts, no easy legs, no forgiveness for a bad plan.

"I trained for six months specifically for this 70.3. Standing at the finish line in Lima, every session was worth it."

What It Feels Like

A 70.3 that reflects Lima: Pacific fog and Peruvian grit. 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 867m 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 Lima 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

→ The bike packs 867m 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.
