The clock runs continuously for 48 hours, including all breaks. The greatest total distance wins; average pace includes stopped time. This is not a Backyard Ultra, where a fixed-distance yard starts every hour.Confirm the record’s surface, athlete classification, race category, ratification status, and date before comparing performances. The mile can refer to a track mile or a road mile; these are distinct record categories. Ultra distances may have additional surface and recognition distinctions.
Running records can change. Always verify official record databases for competition-critical information.
