Last of the Felascans - November 21, 2026

Last of the Felascans is a Backyard Ultra held in Alachau, FL at San Felasco Hammock Preserve State Park and organized by Mule Racing. The race uses a repeating loop format in which participants run a 4.167 mile loop each hour and are eliminated if they fail to complete a loop within the hour. The loop distance equals 100 divided by 24 so a competitor who completes a full day covers 100 miles. There is no predefined finish; the competitor who completes a loop that no other competitor completes is the winner. If no single competitor outlasts every other competitor, there is no winner.

The course follows trails during daylight and a dirt road after dark; there is no pavement on the course. There are no aid stations on course and no aid allowed outside the start/finish area. At the start/finish there will be bathrooms and water and possibly ice. Each runner may use a maximum 10'x10' area for a base camp. Race staff will sound whistles at three, two, and one minute before the start of each loop. Shirts will be provided and the final remaining competitor will receive a special trophy. There are no refunds for runners who drop; their entry fees will be donated to the Friends of San Felasco.

San Felasco Hammock Preserve State Park is a wooded preserve of over 7,000 acres noted for its plant diversity and geological features. Visit the organization's website for the most recent information.
