Big Bear's Backyard Ultra, a backyard ultra event in Zilina, Slovakia, will hold its seventh edition in mid-April. Participants begin simultaneously and continue in the backyard-ultra format: completing one loop at a time. The number of runners decreases as individuals withdraw, fail to start the next loop, or choose to stop.
The prior event commenced on a Friday afternoon and concluded on Saturday, Sunday, or Monday, contingent on the duration the remaining runners maintained their pace. This open-ended conclusion is the primary draw: the event prioritizes endurance, patience, and persistence over a predetermined distance.
