At 8:00 AM on Saturday, November 6th, 2022, we will start the race next to the pond at Pine River Ranch, and the race will use the local trails to complete the loop that is 4.1667 miles.
Each runner has exactly one hour to complete the loop. We will start another race at 0800 hours, where runners race around the same 4.1667 loop. The same will be done at 0900, 1000, 1100, and so on, every hour on the hour.
Runners must be standing in the start line corral when the next race starts. If you are out of the corral, you may not continue. Runners will also not continue if they self-eliminate. No late starts are allowed once the bell is rung.
The Pine River Ranch Backyard Ultra will continue until only one runner remains. At that point, the last runner must complete a loop on their own. If they can complete the loop, then that person is the winner, and all other runners are considered Did Not Finish (DNF).
Racing will continue in the evening and night hours until only one runner has finished the course, so headlamps are encouraged for night-time running.
