Barkley Marathon, USA
- It's categorized as an ultramarathon because its length exceeds 26.2 miles (42.1 km). The full length of the marathon—five loops, roughly 20 miles (32 km) each, which must be completed within 60 hours—tends to exceed 100 miles (160 km) as the route is unmarked and gains thousands of meters of accumulated elevation.

Barkley Marathon, USA
- The race was designed by Gary "Lazarus Lake" Cantrell, who only admits 40 runners each year. Participants are selected through a secretive and unadvertised process in which entrants must write an essay on why they should be allowed to run the marathon. If accepted, they receive a "letter of condolence."

Barkley Marathon, USA
- In a somewhat cruel but hilarious fashion, the race number one is always given to the competitor who seems the least likely to complete one lap. It's said that Lazarus Lake fondly refers to them as a human sacrifice.
