WTF – Wiązowna Trail & Fun is a small cross-country running event in the Wiązowna municipality, a few kilometers from Warsaw. Runners choose between about 5 km and about 10 km, with additional 5 km options for running with a dog and for Nordic Walking. A children’s race of about 500 m is also included, making the event suitable for families and regular trail runners.
The routes are primarily on forest paths in the Celestynów Forest District, offering an off-road feel rather than a city-road format. The field is capped at 500 participants, maintaining a compact size. Advanced runners, amateurs, dog runners, Nordic walkers, and children are all accommodated in the program, with finishers receiving medals. The event aims to encourage physical activity, family sport, and showcase the local forest area around Wiązowna.
