Participation Tips

For First Timers of Time Speed Distance (TSD) Rally:



What is Rallying :


Rallying is a motor sporting event which primarily involves a vehicle, a driver, and a navigator. Some events also allow passengers to sit in the vehicle. Rallying is driving under prescribed speed and through prescribed routes only. Somewhere in the route there are Time Controls (TC) strategically placed by the Organisers, but undisclosed to the competing vehicles. At these Time Controls the Marshal records the time of touching the wheel of the car with the rope laid down on the road. The time is also endorsed in the Time Control Card (TCB) of the competitors.


Enroute the Organisers often strategically place Passage Controls (PC) to ensure that the competing vehicles are traveling through the prescribed route. At Passage Controls time is not endorsed but often the Marshals put their signature on the Time Control Card (TCB).



Finally these timings are used to calculate penalties incurred by the Competing vehicles. The vehicle with the lowest penalty wins the event. In rallying, the skills of both the Driver and the navigator are tested.


Sample of Time Control Card:


Requirement for participation : 


Any person over 18 years and with a valid Driving License can participate in Rallying. He has to have a navigator who will guide him through the event. Certain documents and certain other guidelines as laid down by the governing bodies needs to be followed by each competing vehicle.


Primary documents required :


§     Entry Form

§      Vehicle Registration Book.

§      Tax Book (Tax token)

§      Insurance Documents (Special Rally cover insurance)

§      Driving License.

§      Authority letter from owner of the vehicle if First Driver is not the owner of the competing vehicle.

§     Pollution Under Control Certificate (PUC)

§     FMSCI License

§     Blood Group Certificate

§     Photographs – Minimum 3 copies each







Running of the event: 


At the start of the Rally the navigator is handed over a ROUTE CHART (TULIP) alongwith a SPEED CHART. The navigator then instructs the Driver to follow the route as given in the Tulip. Routes are always given in KM (Kilometer) format with two decimal digits as shown above.


o  0.00 km. -  START POINT

o  0.06 km  -  TAKE RIGHT FROM  ‘Y ‘ FORK 



The Driver / Navigator checks the ODOMETER and follows instruction of the navigator. The Navigator will also call out the average speed that needs to be maintained by the vehicle and it becomes the responsibility of the Driver to adhere to such speed. If the Driver fails to adhere to such speeds they may suddenly find the rope of the TC (TIME CONTROL) visible in the route as TC’s are undisclosed to the competitors. The TC Marshall will note down the Hitting time of the car on his own sheet, which one member of the Crew- i.e. Any member of the competing vehicle has to sign and the TC MARSHALL will also write down the HITTING TIME in the Time Control Card (Time Control Card will be provided at the start of the Rally). 


  • If the Driver did not follow the average speed as called out by the navigator, then he might have either hit the rope late or hit the early.
  • From the start of the event till the end of the route there might be numerous Time Controls and all the Hitting Time will be recorded in the TCB
  • Usually, penalties of hitting early are more than hitting late. The vehicle with the least penalties is adjudged WINNER.


Needless to mention that, vehicles not following the correct route earns more penalties.


A vehicle may stop anywhere in the route but NOT AT ALL at the sight of a TC MARSHALL. This means that as soon as you get to see a TC you cannot STOP at all. Your car’s wheels must be moving (the vehicle may crawl but CANNOT stop). If the Marshall sees you STOPPING or ZIGZAGGING OR REVERSING then you are given Penalties.


After you hit a TC your hitting time is recorded in the TCB. Please ascertain the OD (Official Distance) of the TC by estimation or from the odometer (OD is not disclosed by the Marshall). Remember to start calculating for the next sector (sector is from one TC to another TC) from YOUR ACTUAL HITTING TIME of the last TC.


Calculation Tips for Navigation :




Example :


To ascertain time to travel 9 km at an average speed of 27 :-

Time     = 9   ¸  27 

            =  0.333333333  ®  0 Hrs.

            =  0.333333333 x 60

            =19.99999998    ®  19 Min.

            =  0.99999998 x 60

            =59.99999988    ®  59 Sec.


Therefore, to travel 9 km at an average speed of 27 time required will be 00:19:59.


Motocross is a form of motorcycle racing held on enclosed off road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom. Motocross is a physically demanding sport held in all weather conditions. Modern motocross involves a multitude of styles, and types of racing, exhibitions and vehicles. The rugged terrain used for matches is what influences the design of the bikes and distinguishes them from other types of motorcycles. Motocross is usually held on man-made tracks, at large arenas or football stadiums or race tracks made from dirt and pavement.


The events are usually held at closed courses such as parking lots, small circuits, big ground, stadium or other paved lots. The layout of the course is designed by the organizer and is different for each event.

Due to the tight course layout of gymkhana, smaller / lighter vehicles often have an advantage over larger ones. However, courses may include long straight ways in addition to tight turns, so various sizes and styles of machine are potential contenders.

Motorcycle gymkhana requires technique, ability, knowledge, and motorbike experience. This means riders must not only know techniques of acceleration, braking, reversing but also know tuning the machine to maximize performance. In addition, an analytical mind to assess the course for the most efficient racing lines is essential.

Drag racing

Drag racing is a competition in which prepared automobiles or motorcycles compete two at a time to be the first to cross a set finish line. From a standing START, in a straight line, over a measured distance, most commonly a ¼-mile (402.3-metre / 1,320 ft) on a straight track.

Each driver lines up at the starting line up. Usually Races are started electronically with separate lights for each driver / lane.

Below the staging lights are three large amber lights, a green light, and a red light. When both drivers are staged, the tree is activated to start the race, which causes the three large amber lights to illuminate, followed by the green light. There are two standard light sequences: either the three amber lights flash simultaneously, followed 0.4 seconds later by the green light (a Pro tree), or the ambers light in sequence from top to bottom, 0.5 seconds apart, followed 0.5 seconds later by the green light (a Sportsman tree, or full tree). If the front tires leaves from a stage beam (stage and pre-stage lights both turned off) before the green light illuminates, the red light for that driver's lane illuminates instead, indicating disqualification (unless a more serious violation occurs). Once a driver commits a red-light foul (also known as red lighting), the other driver can also commit a foul start by leaving the line too early but still win, having left later. Should both drivers leave after the green light illuminates, the one leaving first is said to have a holeshot advantage.

The winner is the first vehicle to cross the finish line (and therefore the driver with the lowest total reaction time and elapsed time).

Several measurements are taken for each race: reaction time, elapsed time, and speed. Reaction time is the period from the green light illuminating to the vehicle leaving the starting line. Elapsed time is the period from the vehicle leaving the starting line to crossing the finish line. Speed is measured through a speed trap covering the final 66 feet (20 m) to the finish line, indicating the approximate maximum speed of the vehicle during the run.

In the standard racing format, the losing car and driver are removed from the contest, while the winner goes on to race other winners, until only one is left.
