San Felasco Hammock Preserve State Park is unique and beautiful. As the Friends of San Felasco website states, “San Felasco Hammock was purchased under Florida’s Environmentally Endangered Lands Program in 1974 due to its diversity of plants and geological features. Today at over 7,000 acres, it is one of the largest protected contiguous stands of mesic hammock in Florida.” ( Participants run a 4.167-mile loop every hour, and are eliminated if they fail to complete a loop in an hour. The path of the loop is on trails during the day and along a dirt road after dark (There is no pavement on either course). The distance of each loop is equal to 100 divided by 24, so that a competitor runs 100 miles for a full day of competition. 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.
