Err. You may not have any controls, but actually you would need to be member of one of the clubs using the sports complex Sihlhölzli.
How do I know? I'm trainer of a Karate Club and we have been there for over 40 years.
For precision: the running track is publicy usable, i meant the sports complex itself off course.
