A backyard ultra game
The backyard ultra is the simplest and toughest format in trail running: a 6.706 km loop to finish within the hour, every hour, until only one runner is left. Trail Dynasty plays it out live.
The rules
- A new loop starts every hour, on the hour.
- Each loop is 6.706 km: 24 loops make 100 miles.
- Anyone who is not in the start corral at the whistle, or who finishes a loop after the hour, is out.
- The last one standing must complete one more loop alone to win. If nobody does, there is no winner.
What the manager decides
In a backyard, speed is pointless: every minute saved on the loop is a minute of rest before the next start. You need the right pace, food, a little sleep at night, and to last longer than everyone else.
The live race can last several days, just like the real one. You follow the loops, rest times and DNFs, and adjust the orders.
