Instructions for requesting a wave change

The system automatically assigns starting waves based on the achieved final time from the Jizerská 50 in 2025.

You can request a wave change only based on a demonstrably achieved result from the Worldloppet 2025, 2024 races. A wave change is not possible based on the result from a virtual race or training time. Your request will be approved or rejected based on the documented result.
