The race that’s been called a trail party, where you don’t have to be fast, and where people run way farther than they thought they could. Lastest Not Fastest is a last-person-standing race, also known as a backyard ultra. Everyone starts together and has an hour to complete the 4.13-mile loop. Everyone who makes it in time goes out again on the next hour. And again and again and again, until there is just one person left standing, who is able to complete the final loop by themselves.
