A Backyard Ultra is a form of ultramarathon race where competitors must consecutively run the distance of 6.706kms in less than one hour. When each lap is completed, the remaining time within the hour is used to recover and replenish for the next hours race. The race finishes when one person completes one more lap than anyone else.
We run the backyard for many reasons.
We run because it's fun.
We run to socialise with our friends - old & new.
We run to go further than we have ever gone before ...

The Rules
~ Each loop starts exactly 1 hour after the last one started ... ie: 0830am, 0930am,1030am etc .
~ There will be a warning whistle at 3 minutes, 2 minutes & 1 minute prior to start each hour.
~ If you are not in the starting corral when the bell goes you do not get to start. No late starts. No exceptions.
~ Except for toilet stops runners may not leave the course until each lap is completed. There are flushing toilets in the event village next to the start/finish line and 50m from the start that you run past each lap. No toileting out on course or you risk DQ.
~ No non-competitors on the course including eliminated runners. The tracks are open to the general public including other runners and mountain bikers, please be courteous but accept no assistance.
~ No personal aid during a lap. Aid is only allowed in the event village during the time you have remaining after you have completed a lap and before the start whistle goes for the next lap.
~ Each lap must be completed within the hour to be counted, including the final lap.
~ No artificial aids including poles.
~ Slower runners must allow faster runners to pass. Faster runners must give slower runners time to make room for them to pass. No pushing, shoving or elbowing etc.
~ This is a self supported event in that you must provide all your own food and fluid requirements. We will not be providing an aid station although we will have extra water on hand.
~ The winner is the last person to complete a loop.
~ Everyone else is a DNF.
~ If no one manages to complete a final loop on their own then there is no winner.
~ You must report to the timing team when you decide you cannot go on.
~ Use of noise blocking headphones is strictly prohibited. You must at all times be able to hear approaching cyclists, horses and runners. Use of noise blocking headphones will see you disqualified.
~ A quiet zone will be implemented between dusk and dawn. This is to enable runners and crew as well as volunteers to get some sleep during the night. There will be no music or sound system and crews and friends are to be advised that there is no clapping, yahooing or other verbal cheering on. Silent krayzie dances and wild hand waving is acceptable. Please keep chatter between runners and crew to as quiet as possible so as not to disturb runners in gazebos next to you as they try to catch a few minutes sleep. This also applies inside the lodge where crew members are trying to get some much needed sleep while the runners are on course. Failure to comply may see offending persons removed from the venue.
Compulsory Gear
Due to the lap nature of the event you do not need to carry compulsory gear with you but you must have the following gear at your aid area in the event village:
~ thermal tops and leggings
~ seam sealed jacket
~ spare socks
~ thermal beanie
~ thermal gloves
~ blankets
~ towel

Event Village
Each entrant will be allocated a 3m X 4m space to erect an aid station gazebo for themselves close to the start finish line. This is issued on a first come, first served basis. We will not reserve sites for anyone so please do not ask.
There will be no campers or aid areas with wheels permitted in the Event Village due to damage on the wet grass. You may be able to share a gazebo site with someone else.
For those wishing to stay the night before the event or for support crew during there are cabins and huts available in the camp ground that you can book directly with the park. You can also book a camper/caravan site through the park which is opposite the event village. Make sure you tell them you are part of the event.
We have the lodge with heating and power for supporters to hang out in between laps. There will be hot water available. There will be a place for gadgets to be charged.
There are flushing toilets and hot showers, washing machines and clothes dryers on site. Washing machines & dryers are $4 per usage ... you will need gold coins for these.
Absolutely no support crew or spectators on course at any time.
The Big Question is
Are You Krayzie Enough?
