Unfortunately, some of you had problems logging in and registering for the race. We had to completely reprogram the website in December due to new server generations. Apparently it still had teething problems.

We had two problems:
- Reset password with gmail addresses did not work. This has been corrected and should now work. Please try logging in again.

- Registration form: If the website is set to German DE, everything works. The form did not work for all other languages ​​(EN, FR, IT).

In order to continue to offer you the highest level of security in the future, we had to decide to temporarily deactivate the automatic translation of the website. We are currently examining alternative approaches as to how we can continue to make the website available to you in three national languages ​​(+ English). In the meantime, if necessary, we ask you to use the translation service integrated in your browser.

Maybe you can open two browser windows side by side and compare:
- English to understand the form fields
- German to fill out and register effectively

Don't worry about the early bird price and payment. We will handle this generously.
