Wolf Backyard Ultra Bulgaria 2026

Vladaya village and the northwestern slopes of Vitosha Mountain host this ultimate test of endurance, now in its second year. This is not a race against the clock, but a format designed to find "the most resilient runner" by pushing participants past their physical and mental breaking points. The 6.7 km trail loop above the village features elevation gain that "starts to weigh imperceptibly, then no longer asks". Runners at the start know that rest between loops is part of the race, but also part of the trap. The core rule is simple: there is no second place, only runners who keep going, embodying the spirit that "physical limits are meant to be broken" until a victory is claimed by the last one standing.
