Run the Ganghofer Trail loop, starting at the Wettersteinhalle. The route follows the new cross-country ski track to Kirchplatzl, then along the Leutascher Ache past Platzl and Plaik to Klamm/Obern before returning. An aid station is located at Ostbachbrücke. From there, the course enters the forest towards the lake in Weidach, finishing along the shore and returning to the Wettersteinhalle for a second aid station. Children have age-appropriate routes on forest and dirt paths, avoiding village streets.
