Angelika Joast

🇦🇹 Austria – Solo Swim

was born in a small town in the Austrian Alps. As a child, she loved swimming, but eventually took a 30+ year break from the sport. It wasn’t until the beginning of the pandemic that she decided to join Water World Swim and jump back into the water.

Since then, Angelika has become a dedicated swimmer and has never looked back. She finds peace and solace in the water and loves the challenge of pushing herself to swim farther and faster.

Angelika encourages others to take the plunge and try swimming, even if it has been a while since they last swam. She believes that it is never too late to rediscover the joys of the water.
