Attention: Swim Caps

For sustainability reasons, we have started reducing the number of swim caps where possible.

The caps are arrived anyhow we ask people to use their own ones. Just in case we do have caps for you. The Trial will be provided with our caps to distinguish better.


Parking at Schloss Waldreichs

Please use the rear parking lot 2 at the castle. Signs are posted for guidance. The front parking lot is reserved for regular operations at the bird of prey show and the restaurant.



At Schloss Waldreichs, there is a bird of prey show on Saturday at 11 AM, and the birds can also be viewed from 10 AM onwards. The pond hiking trail from the castle is also recommended, where you can explore the natural surroundings of the region.

It is about 1.5 km to the Dobra, and if you have a bike, you can ride along the Dobra to the dam or the ruins of Dobra. The Schlossstüberl at Schloss Waldreichs is very popular and offers affordable options.


Attention: Swim Caps


For sustainability reasons, we have started to reduce the number of swim caps where possible. Unfortunately, due to issues in the Red Sea, a shipment has not yet arrived, and we can only provide swim caps for the trial distance. We ask all other participants to bring their own swim caps.


Equipment Recommendation:


For organizational reasons, we do not have a vendor on-site this year, but we have prepared the appropriate recommendations for you.


If you need anything, you can order the relevant products from LaufSinn.de or makosport.at, and we will bring them to you.
