Individual Entries

All teams entering the competition automatically enter the individual section of the competition and are therefore legible to win the daily event prizes on offer. Individual teams have to qualify by participating throughout the series, to be invited to the final event which is based on points scored in four events. The main competition prizes are awarded entirely on the team’s performance in this final event.

A team consists of only two people, one driver and one navigator.

Club Spirit Entries

Teams can simultaneously drive for their club and earn points towards the Club Spirit Competition
whilst driving as individuals. We encourage this strongly.

A minimum of 5 entrants is needed to qualify a club into the Spirit Competition, with no limit on how many can enter for a specific club. Points are calculated as follows; 75% of the members entered for a club must attend an event for the club to receive 100% of the attendance points, along with the top five scorers’ points’ contribution in each Club.

Attendance points weigh 50% and driver performances weigh 50% towards the Club’s score of a possible 100 points per event.

For example:

Attendance points: weight 50

Scenario 1: 7 out of nine teams of a Club attend an event, thus 77% attendance. This gives more than 75% attendance, thus 50 points.

Scenario 2: If 5 out of nine teams attend it only gives 55% of the attendance points, thus 27.5 points.

Driving points: Weight 50

Top 5 scores per club contributes 10% each, thus 45 points

The team in the first scenario earns 95 points and in the 2nd scenario only 72.5 points.

The series of events excluding the final event, determines the winner of the “Club Spirit Prize” part of the competition.

Handicap & Bonus system

The aim of the handicap bonus system is to level the playing field so that driver skill is tested above vehicle capabilities.

The following accessory / actions carry a handicap:

  • Front Locker ‐30 points
  • Traction control system ‐30 points
  • DIY body modifications ‐300 points
  • Engine replacement with non standard ‐500 points
  • Vehicle change ‐30 points
  • Driver Change* ‐30 points
  • Navigator Change* ‐30 points
  • Vehicle height vs. wheel base ratio**
  • < 11% 10 points bonus
  • Between 11.01% to 12.50% Zero handicap
  • Between 12.51% to 13.00% ‐10 points
  • Between 13.01% to 13.50% ‐15 points
  • Between 13.51% to 14.00% ‐20 points
  • 14.01% and greater ‐30 points
  • Interfering with the obstacle markers ‐100 points
  • Interfering with the marshal’s duties ‐100 points
  • Moving away from your vehicle at an obstacle to spy on another driver’s approach lines or
    techniques ‐100 points

* The driver or navigator needs to obtain a valid MSA license to participate. Contact us well in advance.

** The Ratio to determine vehicle height is as follows:

  • Ladder frame chassis:
    Measure the ground clearance of the chassis in line with the back end of the front door and divide it by the wheel base measurement and calculate as a percentage.
  • Mono cock chassis:
    Measure the ground clearance from the floor board of the vehicle, not petrol tank, in line with the back end of the front door and divide it by the wheel base measurement and calculate as a percentage

The wheel base measures 2400mm and the height of the vehicle is 200mm
200mm divided by 2400mm x 100/1 = 8.33% thus 10 points bonus.
If the height was 320mm the equation works out to 13.33%, thus 15 points handicap.


Any team can protest, at no cost, as long as the protest procedure is followed in a civilized manner as per the protest form. The protest should be done before handing in the team’s score sheet at race control. Any team who has consumed alcohol, their protest will not be heard.

No verbal protest will be entertained.

Nonsense protests may result in the organizers asking a team not to participate further.

Protest is made in writing to the “Clerk of the course”

Driver / navigator

The navigator may be requested as per the instructions sheet or by the Marshal to remain or exit the vehicle during any of the driving stages.

When replacing a team member, the cost of the new set of official clothing will be for the team’s expense.

Point scoring system

A negative point scoring approach is used with every obstacle counting out of 100 points. The minimum score per obstacle will be Zero.

Marshal Unit

Authority of the Marshal

You are a guest at the marshal point and the marshal is in charge. The Marshal will therefore instruct any team when to proceed and score their actions. The Marshal may stop any team, at any stage for safety reasons by means of blowing on a whistle, this means STOP IMMEDIATELY.


The Marshal may request any person to leave his marshalling area due to interferences. If any such person is a guest / passenger of a specific team, such team will be panalised.


Recoveries will be at the risk of the vehicle owner, thus the vehicle owner is in charge in the event of needing a vehicle recovered. The Marshal may offer assistance or request assistance from another team, depending on the degree of recovery required he or she will inform race control when needed.


The Series consists of a total of seven (7) Driving events of which the last event is by invitation to those teams who qualify. A scattered start approach is used with individual driver briefings.


A team’s top four (4) scores throughout the series of events will be taken into calculation for qualifying to the final. Only 30 teams will be invited to participate in the final.

Every event will consist of 10 obstacles

Guests / Passengers

All catering logistics is based on a two person team. If you want to bring along guests or children you are most welcome, however this may incur extra costs and we ask that you notify us well in advance to eliminate any embarrassment.

The number of guests / passengers in a vehicle is limited by the available working seatbelts.

Guest / Passengers can drive along with you on route, but may be asked to leave the vehicle when driving through point scoring obstacles as determined by the Marshal. Kindly consult with the marshal at the obstacle only when it’s your teams turn to partake and not before as it will be seen as interfering.

The guest / passengers behavior will be the team’s responsibility as certain actions may incur penalties to the team.

Guest / passengers will not be heard as witnesses if a protest is launched.

All guest / passengers must sign an indemnity document.


The cost per team to participate is as follows:
