Unlimited Race Rules
Start:
Each lap starts precisely on the hour, every hour.
Runners must be in the starting corral at the bell.
Warnings are given at 3, 2, and 1 minute(s) before each start.
All competitors must start at the bell (no late starts); missing the start means elimination.
During the Lap:
Each lap must be completed within one hour, including the final lap.
Runners may only leave the course to use the restroom.
No non-competitors (including eliminated runners) are allowed on the course.
No personal aid is allowed during a lap (common aid stations are permitted at the start/finish area only).
No artificial aids (e.g., trekking poles) or pacers are allowed.
Slower runners must allow faster runners to pass.
Between Laps:
Any remaining time after finishing a lap can be used for rest, food, or preparation for the next lap.
Elimination:
Failing to finish a lap within the hour, not starting at the bell, or voluntarily quitting results in elimination (marked as DNF—Did Not Finish).
Winner Determination:
The winner is the last person to complete a lap on their own; all others receive a DNF.
If no runner completes one more lap than the others, there is no winner.
Time Limited Race Rules (24, 12, and 6 hours)
General Format
The same rules as the standard backyard ultra apply regarding lap distance, start, aid, and elimination.
The event is capped at a set number of hours or laps (e.g., 12 hours, 24 hours, or a set number of loops).
Winner Determination in Time-Limited Events:
The runner who completes the most laps within the time limit is the winner.
If multiple runners complete the same number of laps, the fastest cumulative time for all completed laps may be used as a tiebreaker (if specified by the event).
If all runners complete the maximum number of laps, there may be multiple finishers.
