Big Bears Backyard Ultra

About this event

Big Bears Backyard Ultra brings the unique backyard format to the scenic region of Žilina in northern Slovakia. Following the signature style popularized by Lazarus Lake, runners tackle a 6.7km loop every hour on the hour, continuing until only one person remains. The event tests mental fortitude as much as physical endurance, with the mountainous terrain of the Žilina area adding its own challenge to an already demanding format. Set against the backdrop of the Malá Fatra mountains, this event suits experienced ultra runners ready to push their limits in a distinctive competition where strategy, pacing, and sheer determination matter as much as raw speed.
