Overview
Ultramaratón Zárate 6h was a timed track event held in Zarate, Argentina, organised by Nesteruk - Burafi - Scoglia. Measured strictly by the clock rather than a set course distance, runners managed their own pacing across a fixed 6 hours of continuous running.
Competition took place entirely on an 816 asphalt velodrome circuit, requiring competitors to settle into a repetitive rhythm while managing ongoing nutrition and lap counting from the trackside. The format featured remaining-meter measurement at the final whistle, ensuring every meter gained beyond the completed 816 circuit loops counted directly toward each runner's final total.
