Ironman 70.3 New Zealand

Few races offer you a dip in the caldera of a supervolcano before you even hop on your bike 🌋. The IRONMAN 70.3 New Zealand rises to this challenge every year in Taupō, on the North Island of New Zealand, in a setting straight out of a fantasy film. Held on the fringe of the legendary IRONMAN New Zealand, the second oldest of its kind in the world, this “half-distance” format brings together almost 2,000 athletes from around the globe 🌏. Three disciplines, one day, and a giant lake as the playground 💪.

The premise of a 70.3 is in its name: 70.3 miles in total, which is 113 km divided into three segments ⏱. First up 1.9 km of open-water swimming before hitting 90 km of cycling, then closing with a half-marathon of 21.1 km 🚴. A wetsuit is de rigueur for swimming, as the lake water hovers around 19 °C, enough to wake the bodies up at dawn 🥶. Solo start for the bravest, or a two-or three relay to share the effort with friends. A performance here even opens the doors to the 70.3 World Championship, raising the stakes 🥇.

The course, meanwhile, goes for natural grandeur 🌊. The swim takes place in the Taupo Lake, the largest freshwater body in Oceania, often wrapped in mystical morning mist. The bike then winds through Waikato’s hills and farms, before the run brings triathletes back to the shores for two laps along the lakefront 🏃. In the backdrop stand the volcanoes of the Tongariro National Park, made famous by the saga of the Lord of the Rings, while the famous red-carpet finish, in the city center, offers one of the loudest finales on the circuit 📣.

Taupō and triathlon have been in perfect harmony for decades 🔥. Born in 1985 in Auckland, the New Zealand IRONMAN planted its roots here in 1999, finding a spiritual home in this tiny spa town. The 70.3 version today stands as an ideal stepping stone toward the full distance, more approachable but never a stroll in the park. Surrounding it is an army of more than 2,000 volunteers, nicknamed the whānau Ironman after the Maori name for the big family, watching over athletes until the last finisher of the night 🤝.

The big differentiator of the event lies beneath the surface 🌋. The Taupo Lake is none other than the caldera of a supervolcano, whose eruption about 27,000 years ago ranks among the most violent ever recorded, to the point of covering the entire island in ash. Swimming in water as pure as a mountain lake, knowing what lies beneath, adds a thrill all its own to the adventure 😮. On race day, the whole town holds its breath and hums to the rhythm of the triathlon, turning this volcanic natural corner into an open-air arena 🎉.

Taupō isn’t just about welcoming triathletes: the small town has also earned a solid reputation as the adventure capital 🪂. Nearby, the Huka Falls unleash a flow so powerful that it would fill an Olympic-sized pool in seconds, and the surrounding volcanic ranges offer one of the country’s finest hikes, the Tongariro Alpine Crossing ⛰. Between skydiving, hot springs and otherworldly landscapes, it’s hard not to leave with one last adrenaline shot 🔥.

So Tony Stark, are you ready? 🦸
