Prize: The winner of the Last Runner Standing event will win a dollar for every mile they run, and the seconder will win a dollar for every yard they finish!
Backyard Format Rules: 100 miles divided into 24 hours give you 4.167 miles for a "yard" (lap). Every hour, on the hour, a new yard will start and you must finish within the hour and be back in the starting corral for the next one to stay in the run. Complete as many as you can, the last runner standing wins.
