Dusk till Dawn Rules and Tips

There are no formal official National rules regulating endurance mountain bike racing, generally the rules for most 12-hour events have evolved over time, as the race format grows. Commonsense should apply at all times. Rules may differ from event to event, and what may apply in one event may not apply in another. Please understand this and read the rules for each race. The current rules for the 12 Hour MTB Race is here.


The Dusk till Dawn is run under the auspices and general guidelines of MTBA including the permission of ASDA to attend the event.

The Course

Race Course. The course will be set and marked one week before the event. It is roughly a 13 to 15km loop consisting consisting of single-track, and fire road. It will be marked by the use of a mixture of arrows, bunting, and crowd control barriers. There will be sections throughout the course where there are no markings however there will also be no decision points either just keep riding. At each decision point (which way now!) the course will be marked. At the end of each lap the course passes through the Timing Tent and Transition Zone. As in 2015 there will be figure 8 with a cross over at the main event village, this ensure we can run the course to incorporate its best features and it will run the in the regular direction in 2016.

Emergency Access/Checkpoints. If you come across a rider who are in trouble physically you MUST stop. When the next rider on track comes past one of you must continue on to raise the attention of a marshal while someone stays with the distressed rider. Please take note of the nearest emergency access point sign when alerting the marshal. This will help us to get to the injured rider quickly. Both riders times will be reviewed accordingly. Any rider who does not offer assistance may be disqualified from the race. There will be at least six emergency access points around the course.

Course Modifications.
The Race Director and Trail Crew may need to alter the course at any time throughout the race. This will be done only in extreme circumstances that could include diversions due to excessive rainfall, mudslides, fallen trees, track damage or any other form of development necessitating a course change. The course modification will be made so as to limit any disadvantage to any individual team.

Emergency Vehicles.
If an injured rider has to be evacuated, then an emergency vehicle may have to move through the Forest to conduct the evacuation. The Emergency Vehicle will have hazard lights and headlights on at all times. Riders should slow down to let the vehicle pass if required.

Rider and Bike

Helmets. All riders must wear an Australian Standards approved cycling helmet whilst riding a bike at the 12hr race or a helmet of acceptable international standard as published on the MTBA website from time to time.

Race Numbers and timing. Each rider is given an individual race number. This must be fitted to the handlebar area of the bike in order for your lap to be timed and counted you must ensure that your race number is legible (zip ties are provided). Do not deface, or trim the race plate smaller or wrap it around your cables in such a way that it is not legible. If timing cannot read your number, your time may not be recorded and your lap time will not count. Your race number is yours to keep after the event; it will make a great souvenir over the bar.

Fit to Ride. If in the opinion of a Transition Marshal or the Race Director, it appears that a rider is not fit to ride, that rider will be directed to be reviewed by the First Aid crew before being allowed to commence a lap. Fit to ride means that you are capable of completing a lap without endangering yourself or other competitors. The decision to be allowed to continue to race rests with the advice received from the first aid crew and will be applied absolutely. Teams can swap the rider for a fitter rider, so that the team doesnt lose time. We actively encourage teams to undertake this review pre-transition, as part of normal team management and for team captains to ensure that their riders are fit to ride.

Registered Riders Only. Only registered riders and those given approval from the Race Director (eg: first aid, media and course sweeps) are allowed onto the course. Spectators are permitted on the course but are asked not impede the riders in any way.

Licence. All riders must have an MTBA licence/ receipt or have purchased a 'Day licence' before riding on the course. Only nominated team members can race. No new members can compete after the race has commenced.

Outside assistance. This race is run under a "Full Assistance" policy. A rider may receive technical and mechanical help from anyone, anywhere on the track.
That assistance must not impede other riders.
The rider/bike must enter the course AT or BEFORE the point where they left the track.
In order to record a time or to transition to the next rider the rider and THE COMPLETE BIKE regardless of how many pieces it may be in must follow the track to the end ONLY powered by the RIDER (ie No assistance in carrying the bike).
In instances where riders are assisted back to transition the team/individual SHALL INFORM THE RACE DIRECTOR the Race Director may: Add time or subtract place.

Types of Bikes. Serviceable and rideable Mountain Bikes suitable for off-road use are allowed. Both front and rear brakes must be in good working order. Whether the bike is geared or singlespeed is entirely up to you. You may change bikes as many times as you like between laps. Other bikes may be allowed at the discretion of the Race Director. Tandems are not permitted on the course.

Lights. All competitors must use adequate front lighting on their bike or person after the designated time for night laps. For safety reasons and also for enjoyment of night riding it is advised to use a good quality bike light so you can see where you are going. All competitors must have a red rear light (not on flashing mode please) affixed to their bike or person at all times. Additionally, an emergency front light is also required should your main light fail (a head torch, flashlight, etc will suffice). The Transition zone staff will not let you enter the course unless you have the lights on your bike or person.

Equipment. Riders are to ensure that they carry an adequate supply of water or other appropriate fluids, a full water bottle or equivalent in a hydration bladder when leaving transition. It is recommended that riders also carry puncture repair equipment at all times and lights when applicable.

If you carried or rode it in, then carry or ride it out. Dont trash the track, there will be Feed Zone Bins out on the course so if you need to dispose of rubbish, ruined tubes, broken chains etc then please use the bins or bring it back to transition. Leave nothing except footprints and tyre tracks.

Rider Etiquette. 12 hour racing is known and valued for good sportsmanship. Lets keep that tradition alive for the Dusk Till Dawn again this year. We want everyone to have a positive experience during this event, and good attitudes while out on the track will go a long way to make it a great event for all. (Note: Poor sportsmanship may result in rider disqualification and is at the sole discretion of the Race Director).

Overtaking. Riding on a course with up to 300 others means that you will be passed or will be overtaking a lot. This must be done safely and it is hoped with a positive attitude and good communication. A simple call of Track by the overtaking rider alerts the slower rider that you are there and want to overtake. The slower rider should then pick a spot where they can safely overtake. The slower rider could use terms like Now meaning that he/she is ready for you to overtake and the slower rider or may even call out My Left or My Right. You then quickly accelerate past the rider on the side indicated. You can also call out On your left or On your right to indicate which side you are passing on. It sounds complicated, but essentially it takes just seconds to complete. As the overtaking rider, dont expect miracles as riders of varying abilities compete in 12 hours events and the rider in front will choose when it is safe for them to pull over and let you by. Slower riders should not deliberately impede faster riders however. The rider being overtaken has right-of-way until the overtaking rider is past and clear by a bike length. Yelling track from 25m away is not productive either, you must be close to the rider you wish to pass, not just trying to clear the road ahead. At all times, rider walking their bike must step off course to give way to a rider who is riding.


The Transition Zone (TZ) is the area where you swap riders. You must touch to hand over to the next rider so be careful. It is generally confusing and noisy, however, dont stress out in the TZ, after clearing the timing chute, move through and call out your team mates name or team name, more than likely your team mate is waiting for you and making their way into the TZ to do the changeover. If your rider cannot be located, attract the attention of the man with the microphone who will call out your team name and usually the riders name as well.

When leaving the transition please give way to riders who are already on the course and coming through or across the figure 8 transition. This race is not a sprint so there is no need to be concerned and as always safety is paramount.

As you come through the TZ, there are a few simple rules to make life easier for everyone
1. Please slow down. Go around transition if you are going out for another lap.
2. Dont crowd the Timing Chute, hang back a bit as your chance will come.
3. Move forward about 10 metres past the end of the timing chute before calling out for your rider

Helpful hints for a smooth transition

- Dont expect a Grand Prix changeover (it isnt going to happen)
- Help your team mate with the transition
- After you have completed the transition, VERY promptly clear the area and move outside the TZ to catch your breath, have a chat or warm down

Timing/results. The individual/team with the most laps wins the event. For teams on the same number of laps, the team with the fastest time wins. The race starts when the timing clock starts and finishes 12:00 hours later. No riders will be permitted on the track after 5:40am. Anyone finishing after 6:00am will not have their last lap counted.

Results. Live results will be available throughout the night. Go to the timing tent to use the available computer or get the barcode to access the website on your mobile phone. At times the timing team may be doing adjustments/corrections so please give them room to do this.
Final Results will be available as soon as the last rider clears the course, and presentations begin, unless there is a protest. All results will be posted on the WA 12hr website as soon as practicable after the race.

Finishers. All teams that complete at least one lap will be registered as a finishing team. You can finish the event at anytime however you maximize your potential for a category place by riding for the whole 12 hours (and achieve hero status to boot). Riders and teams can take a break at anytime throughout the event and your lap time is measured from when your previous team rider finishes a lap until you complete the next lap. To be eligible for a place getter prize in solo categories you MUST have ridden for at least 9 hours.

Accidents. If a rider comes across an accident they must stop to see if the fallen rider is ok and wait for the next rider to come along so that a message can be passed to the next checkpoint. Please pass on the information of the kms mark from the start and the injured rider's number. If the injury appears serious call "000" immediately.

Amendments. These rules may be amended until Thursday 12:00 Nov 08. A full copy of the race rules will be held by the Race Director at the Timing Tent.

Protest will be heard in accordance with MTBA general guidelines. A copy of which is held by the Race Director at the Timing Tent. Any and all protests must be lodged with the race director within 15 mins of the race end.

Race Directors Decision.
After giving due consideration to all parties, the Race Directors decision is final.
