Trailo kalvės S4E4. Prienai

Trailo Kalvė S4E4 Prienai is a winter trail running event held at the Giraitiškės recreation area in Prienai. This stage traditionally took place in autumn, but this season participants are invited to take on the course in winter. The event offers routes of various lengths for runners of different ages and experience levels, from children to adults. It is part of the Trailo Kalvė Cup, which features routes of varying difficulty and elevation gain.

There are no medals, but participants registering for the first time this season receive a Trailo Kalvė running band. The event takes place in winter, so the routes are snow-covered and require special preparation. Registration is available only for team participants; regular tickets are recommended for individual entries. Participants are encouraged to register in teams. The event takes place at the Giraitiškės recreation area, and the course is run in winter conditions.
