Welcome to the Brunei Backyard Ultra!
This race is open to everyone, but there can only be one finisher. The Backyard Ultra is a type of ultramarathon where participants must run a distance of 6706 meters (4.167 miles) in less than one hour, and any remaining time within the hour after completing the lap should be used for rest and refueling.
This race is well known for its strict rules;
- No Late Start.
- Each loop starts precisely one hour.
- You are counted as withdrawing if you are not at the starting line at that hour.
- Please don’t leave the course until every loop is completed.
- No non-participants, personal aid (support crew) or artificial aid such as trekking poles on the course.
- The winner is the last person to complete a loop. All others are technically DNF. There is no winner if no runner can complete one more loop than anyone else.
