Gravity Enduro South Australia (GESA) is dedicated to bringing gravity enduro mountain biking to Adelaide and its surrounding areas.

We like to keep things simple and fun. You can come out to vie for the top step on the podium or you can keep things more casual and have a fun day out on the bike.

Our race format and rules are based on the Enduro World Series (EWS). A course has a number of timed descending special stages linked together with untimed liaison stages. Riders must get through the entire course under their own steam within a set time limit. Gravity Enduro racing is undertaken with limited practice and rewards the best all round riders - not just the riders with the most time to practice.

Through hard work, steep learning curves and successful events, our race series continues to grow and the Enduro community continues to thrive. We’re proud of what we’ve created and look forward to more good times in the future.


The Rules

The rules are here to keep everyone safe and ensure good sportsmanship. Whether you’re an Elite racer or a weekend warrior, the same rules apply. Not respecting the rules will result in a time penalty, disqualification or potential ban from racing.


  • Be courteous

  • Remember, this is not the EWS

  • The officials are only human

  • The volunteers have been here for hours setting up so you can race

  • Respect the trails. Do not cut corners or create new lines.

  • Before you complain, have you volunteered?


Rider Responsibilities

  • Read the rules

  • Ride within your limits

  • Ensure your bike is in good working order before the race

  • Eyes up! Read the trail.

  • Help injured riders. If you are first on the scene of an accident, make sure everyone involved is OK, if there is an injury, stay with them and organise the next rider past to go for help. DO NOT leave a seriously injured rider by themselves. 


  • The entire course must be completed under the rider’s own power. No assistance is permitted on race or liaison stages.

  • Only one attempt per time stage is permitted.

  • Catching riders on course is part of racing. If a rider behind you has given ample time and they catch you on the stage, you must move aside.

o   If you want to overtake a rider, clearly and politely let the rider in front know – ‘rider when ready’ is a good approach

o   If you are being overtaken, move over as soon as it is safe to do so

o   Please and Thank you go a long way

  • The only instance where a re-run of a stage is permitted is if you stop to help an injured rider. You must pass the finish beacon first, notify the marshal and proceed to the start of the stage following the liaison route.

  • If you cause a rider to crash due to an unsafe pass you will be disqualified.

  • Riders who wish to not complete the course must proceed to the registration tent and follow instructions.

  • Once you finish the course, return to the registration tent where your times will be uploaded from the timing chip


The Course

We try to run an inclusive race series allowing differently skilled riders to compete on the same course. The course will consist of:

  • Descents on technical trails with options of ‘A’ lines and ‘B’ lines if appropriate

    • ‘A’ line is usually the more difficult but the quickest path

    • ‘B’ line may direct a rider around a technical trail feature and is usually the slower, although easier path.

  • Short flat or climbing sections may be included in timed stages in accordance with EWS guidelines

  • Timed stages are linked together by generally un-timed climbs or liaisons, however there is an overall time cap in which the course must be completed. Dawdling, stopping for food or visiting your car is no excuse for a slow course completion time. If you run into any problems, notify a marshal immediately.

  • Proceed with caution if you are unsure of the course.

  • It is the rider’s responsibility to read the trail markings. Don’t assume a stage will be marked in a certain way

  • Course details will be made public on the Friday prior to race day

  • Riders check in and out of special stages by passing the start and finish beacons

  • Stages are designed to suit a mid-travel bike but can be completed on any bike with varying degrees of difficulty

  • Course will be marked out with arrows, bunting and sign posts to indicate the direction of travel.

  • The course is usually made up of 4 to 7 stages and depending on the event, can range from 10-25mins of race time and/or 15-25kms

  • Taking short cuts is not in the spirit of fair competition, may cause damage to the surrounding environment and will result in a disqualification and potential ban from all future events. A short cut is any line that deviates from the established trail in order to gain a time advantage whether or not there is bunting in place. The bunting is there to indicate that you are heading in the right direction not to define the track limits. 

  • If you leave the course on a race stage you must re-enter the track in the same place

  • If a rider is caught short cutting or unfairly gaining an advantage by a marshal, they may be disqualified

  • If a rider is reported short cutting or unfairly gaining an advantage by 3 or more riders or spectators, they may be disqualified


  • Riders will receive a timing chip at registration to be worn on your wrist.

  • The chip must be activated at registration. If you don't activate it, it won't work, and you won't get any results.

  • The chip is the rider’s responsibility to keep safe for the duration of the race. If lost or broken, the rider will be charged for the replacement (approximately $150)

  • Upon completing the course riders must go straight to the timing tent to download their times and return their timing chip.



  • You may only use one bike during the event. Wheel rims, bike frame and fork cannot be changed. The race director has the discretion to prohibit unsafe or unsuitable bikes

  • All bikes must be in perfect working order

  • Bikes can be repaired during the event, but no extra time is granted

  • Competitors are not to modify race plates

Personal equipment

  • Full face helmets that meet Australian Standards are compulsory on timed stages for all riders

  • Helmets with a detachable chin piece are acceptable

  • Open faced helmets are permitted for non-competitive liaison stages only

  • Riders must wear a helmet whenever they are riding their bike

  • Riders must carry enough food and water to get around the course

Optional (but recommended):


Knee and elbow pads

Mobile Phone

Bike repair kit. ie Tubes, pump, etc


*Although every effort will be made to contact all competitors, GESA reserves the right to make changes to the rules at any given time without notice
