Rules
- The distance of the yard (loop) is 6.705 km, equivalent to 4 miles 880 feet.
- The start and end point are the same throughout the CBU and participants must be in the start at the bell. Warning bell is given 3, 2, and 1 minutes prior to start.
- Starts. Every yard starts precisely an hour after the last one. Runners have a 59-minute and 59-second limit to complete it, including the final lap. Failure to finish within this time or failure to start at the bell (no late starts) results in disqualification, and the runner must surrender their BIB NUMBER.
- Each athlete has the right to rest during the time remaining before the next loop starts. For example, if a runner finishes at 45 minutes, they have a 15-minute rest until the next cycle begins. All runners start together at designated times (e.g., 10:00, 11:00, 12:00, etc.).
- Runners are allowed to carry their own food and water during the race.
- Runners must stay on the designated course during each loop, except for restrooms.
- Artificial aids (including trekking poles), pacing and escorting by other athletes who have withdrawn from the race or non-participants are prohibited.
- Music is permitted, but headphones must be removed upon reaching the start/finish area to communicate with the race officials.
- All athletes must wear their BIB NUMBER visibly on the front.
- Any runner caught deviating from the designated route will be disqualified.
- Final results will be posted on the official Backyard Ultra website and on the DUV database, including a global ranking and a national ranking for Cyprus based on the number of loops completed by each runner.
- The winner is the last runner remaining to complete a loop alone. If no runner can complete another loop solo, there is no winner. Total distance covered by each runner will also be recorded. All other participants are technically DNF.
- The race is open ended.
