Delta Backyard Ultra rules:

1. The race starts at 7:00am on Sunday, 1 May 2022. 
2. You will need to be in the starting corral before the yard starts, and leave when the siren sounds to signify the start of the yard (no late starts).
3. Each yard will start exactly one hour after the previous yard started. You will be given 3, 2, and 1-minute warnings prior to the start of the next yard.
4. Each loop must be completed within an hour to be counted, including the final lap.
5. Except for restrooms, you are not permitted to leave the course until each yard is completed.
6. You may have as many supporters as you wish with you in Camp Delta, where you and your supports are allowed  to set up camp within a demarkated area.
7. There is no requirement for any compulsory gear while you are running a given yard. Headphones may be worn throughout your race. 
8. You may not use any artificial aids (e.g. trekking poles) or personal aid (e.g. supporter/ seconder or pacer) to assist you during your race.
9. Non-competitors (including eliminated runners) are not allowed to start and run the yard with competitors.
10. Your race will be over if you fail to be in the start corral before the siren sounds or if you don’t complete the yard within the given hour.
11. The winner of DBU is the last person to complete a yard. If no runner can complete one more yard than anyone else within an hour, there is no winner – everyone is a DNF (Did Not Finish).
