For a free trial participation send us an email and we'll make an appointment. Within a 4 weeks trials period you'll then have the opportunity to try out the sports you're interested in (each sport twice). For the trial period, please fill in and sign our Teilnahmeformular. You can do so on-site (we have always printed forms with us) or bring with you an already filled and signed form. The trial period can not be extended or renewed.
