The Backyard format is simple: 100 miles divided into 24 hours give you 4.167 miles for a "yard" (lap). Every hour, on the hour, a new yard will start, and you must finish within the hour and be back in the starting corral for the next one to stay in the run. Complete as many as you can, last runner standing wins. Runners and crew will be able to set up a personal area with chairs, tents, etc. around the start/finish course-line area for personal aid, gear, and rest between yards (not during). We will give a 3-minute, 2-minute, and 1-minute warning to be inside the starting corral for the next yard. All runners are required to be in the starting corral before the top of the hour. Failure to line up in the starting corral will result in the disqualification of the runner. Participants must start a new yard at the sound and continue out on the course (not back to their tent, etc.). Once you are on the course, you are not allowed any aid from your crew or any other individual. No non-competitors on the course (including eliminated runners). Except for restrooms, competitors may not leave the course until each loop is completed. Runners are responsible for their own aid on the course (carried with them). You must be on and stay on the course unless you need to use the bathroom. No artificial aids (including trekking poles) are allowed. Once you complete the yard, and assuming you have finished within the hour, you may use the bathroom, eat, drink, sleep, ponder the next yard, etc., but you MUST be back in the start corral at the beginning of the hour to continue into the next hour’s yard. Runners will continue until ONE runner completes a FINAL lap. (i.e. If there are two runners left and one does not complete the loop, then the one that completed the loop will be declared the winner). No pacers whatsoever. You must checkout with the race director once you can not complete a yard or decide not to begin the next yard. ​There will be limited water provided at the start/finish however each runner must be self-sufficient with respect to their own nutritional needs. Any runner still on course after 7pm (19h00), must have a working headlamp. Any runner lining up without a working headlamp will be disqualified. Runners may carry drinks and food to drink/eat on the course. All empty bottles and wrappers to be carried with you to the finish. Anybody found intentionally littering on the course will be immediately disqualified. There are no medical staff at the race. Each runner is expected to look after their own safety. If there is a medical emergency, we will assist where possible but do not accept any responsibility for any injuries or damage sustained during the event. Runners to please collect any litter that they see on the course. Cooler boxes will be allowed for runners. Supporters are encouraged to support the venue’s bar. Runners must obey any instruction given to them by any of the race officials. Failure to follow a valid instruction will result in immediate disqualification.
