Last of the Felascans : Nov 22, 2025

This event is a Backyard Ultra held in Alachau, FL. Participants run a 4.167-mile loop every hour and are eliminated if they fail to complete a loop within the hour. The loop distance is equal to 100 divided by 24, so a competitor who completes a full day of the event will have run 100 miles. The course is on trails during daytime and on a dirt road after dark; there is no pavement on either course. There is no predefined finish; the winner is the competitor who completes a loop that no other competitors complete. If no competitor outlasts every other competitor, there is no winner.
