I Lesny Bieg Gminy Brzeznio Tumidaj

Tumidaj’s forest run is a local trail event in Poland’s Gmina Brzeźnio, set for mid-June. Participants can select between 5 km or 10 km, placing it in the short-distance category of trail racing, distinct from the ultra scene. The course details are limited, but the event's name and listings suggest a forest path rather than a road race. The program also features a Family Run and Nordic Walking, indicating it functions more as a community sports day organized by the Brzeźnio municipality, rather than a competition exclusively for runners.
