Stumilak

Stumilak is a Polish mountain trail series held in Zawoja in early June. Participants can select from three long distances: 80 km, 100 km, and 160 km, all designated as UTMB Index races. The 160 km route presents the greatest challenge on paper, featuring 9,110 metres of elevation gain over its length. The races follow city-to-city trails through the forests and mountains of the Bieszczady range. The 100 km distance is the most frequently chosen, measuring approximately 103.7 km with 5,330 metres of elevation gain. Recent results for this distance indicate a small group of 23 finishers, suggesting it is a demanding race for specialists rather than a large-scale event.
