TSD Rallying

TSD Rallying is also known as Regularity Rallying. It is a form of motorsport which can be done by anyone with any motorised vehicle having normal driving skills and well versed with the usage of this simple formula

Speed = Distance / Time

The object of these rallies is to maintain precise times and precise average speeds given on the various segments of a predefined route and are penalised according to time taken by them in completing one segment at the given average speed.

Each team consists of a driver and a navigator and the teams are given start at a regular interval.

A schedule is given to each team prior the start of the rally and is briefed about the stages and challenges which will be faced by them. Along the route the team will encounter Marshals which who note the exact time in the defined format at which you have reached them which will be used in scoring. The position at which a team encounter Marshals is known as Time Check (TC) point. The position of Marshalls is generally not known to the teams prior to the rally and they will be noting their times as the teams reach their location.

There might be various other features added to the above basic format which are discussed in the competitor’s briefing which is very important for a team to attend.

The scoring is done on an ideal time basis calculation. Here is an example for this :-

Suppose the average speed given for a stage is 30 Km/hr and the Marshalls are placed at positions 30 Km (TC-1) and  45 Km(TC-2) from the start position whose reading is taken as 0 Km(TC-0). A team is given start from TC-0 and the time is noted there suppose here it is 10:00:00 ( HH:MM:SS)

So, according to the above formula, the time that must be taken to reach TC-1 should be

Ideal Time = Distance between TC-0 and TC-1 / Average Speed

Ideal Time = 30 / 30 = 01:00:00 Hr

Similarly Ideal Time to reach TC-2 can be calculated as

Ideal Time = Distance between TC-1 and TC-2 / Average Speed

Ideal Time = 45 – 30 / 30 = 15/30 = 00:30:00 Hr

So, the ideal time to cover the distance between TC-1 and TC-2 is 00:30:00 Hr.

So, the ideal time to cover the distance between TC-0 and TC-1 must be 01:00:00 Hr and TC-1 and TC-2 is 00:30:00 Hr .That means, if a team is given start at 10:00:00 Hrs should reach TC-1 location by 11:00:00 Hrs and TC-2 location by 11:30:00 Hrs to be exempted from any penalty points. And, if it takes more or less time than the calculated ideal time then the team is subjected for penalties which are mentioned in the regulations or are explained in the competitor’s briefing session.
