While Stève Stievenart is relentless, the sea is unforgiving.
This collision between the Frenchman and Mother Nature can be slow moving and intense, but Stievenart refuses to bend, refuses to yield.
That mindset and physicality enabled Stievenart (48, France, MSF bio here, IISA bio here) to become history’s first person to achieve the Triple Corona del Fin del Mundo (Triple Crown of the End of the World). It was another achievement in the prolific career of the International Marathon Swimming Hall of Famer from from Wimereux, France.
- Cruce a Nado del Canal Beagle between Chile and Uruguay in 53 minutes 24 seconds in 8°C water
- Cruce a Nado del Estrecho de Magallanes, a 5 km crossing within Chilean waters in 1 hour 50 minutes 2 seconds on April 11th
- Cruce a Nado del Río de la Plata, a 42 km crossing from Uruguay to Argentina in 17 hours 59 minutes 33 seconds on April 19th
The last swim was tough. “I had waves and wind the whole time, not a moment of calm,” the 48-year-old swimmer said. “Río de la Plata is something you have to earn! It was a grueling day. I’m super happy because I’m the first swimmer to do it, it’s a double satisfaction.”
