Ines Hahn [shown on left] tried her hand on the professional marathon swimming circuit, competing from Cancun, Mexico to Quebec, Canada.

But the 25-year-old from Germany has really found her niche in ice swimming; the cold is clearly her realm of expertise.

She was non-stop at the 2017 Ice Swimming Aqua Sphere World Championships in Burghausen, Germany this past weekend.

On Day One, she finished second in the featured 1000m ice kilometer to German teammate Julia Wittig. But it was Day Three where she really shined despite the thick blanket of snow that covered Herrenbad, the famed Bavarian ice swimming venue.

She qualified for the SuperFinal in the 100m individual medley in the 3.4°C (38°F) water as well as the 200m freestyle and 500m freestyle.

She finished third in 100m IM in 1:15.4, won the 200m in 2:22.5 by nearly 9 seconds, and won the 500m in a thrilling shoulder-to-shoulder race against her chief rival Wittig in 6:17.8.

This meant that Hahn swam a total of 2,600 meters throughout the event in water that ranged from nearly 0°C at the surface to a maximum of 3.6°C underneath in Lake Wöhrsee, nearly always with a wide smile on her face.
