"The adrenaline you get while kite-surfing gives you a lot of positive energy for the whole day." - she says in an interview for "Naised" magazine. She remembers however, to remain careful: "I know you shouldn't overestimate your abilities."
She's also reasonable on the beach: "When I go sunbathing I always take some sun lotion, something to cover my head with and a bottle of water. I don't tend to swim in deep water and I try to keep an eye on the others so, if necessary, I could go for help or persuade the drunk ones not to go into the water."
The interesting fact is that Katrin is afraid of thundrstorms. She says she always unplugs all electrical devices and stays as far from windows as possible during one.
