The Swiss speedster broke Chrissie Wellington’s course record here last year with a winning time of 8 hours, 51 minutes, and 24 seconds.

Ryf says, “I really loved the atmosphere last year and I enjoyed racing in Germany. The training was good and I’m looking forward to see how fast my legs will go this year.”

The reigning Ironman World Champion will face a high-caliber field with the likes of former Ironman 70.3 World Champion Melissa Hauschildt of Australia, fellow Swiss Emma Bilham, and Germany’s top female athletes including Diana Riesler.
