Default Re: Explained! TSD (Time-Speed-Distance) Rallying

Fantastic thread. Thanks Sudev this clarified a lot of doubts I had about the TSD format.

My one and only experience with this was during the http://www.team-bhp.com/forum/indian...ge-2012-a.html (A Report on the Mahindra Adventure: Monsoon Challenge 2012)

I had no idea when we set out just how much fun and excitement is possible in a "slow" race.
I was simply stunned when I saw the winner of that contest having almost 0 time difference.

Before you say it is difficult to participate in events so far away let me share that events are happening all over.

Few of the biggest events that happen in TSD format are as follows:
• Desert Storm - Delhi
• Raid De Himalaya - Shimla
• SJOBA Rally - Chandigarh
• Taj Rally - Agra
• Royal Rajasthan - Jaipur
• Kaviguru Rally - Kolkata
• Mahindra Adventure - Nashik
• Dakshin Dare - Bangluru
• Rally of Jeypore
• Rally of Coimbatore
• Green Run - Bangluru
• Monsoon Run - Kolkata
• Grand Krishna - Chikmanglur
• Orange Adventure - Chikmanglur
• Malwa TSD - Indore
• Drive to Cause - Kolkata
• Silver Spring - Kolkata
• Spirit of Kalinga - Bhubaneswar
• Indo Bhutan - Siliguri

There is also a six to nine round national championship conducted by Federation of Motor Sports Clubs of India (FMSCI) every year. There are many more one day or half day events with concentration around Kolkata, Bangalore, Coimbatore and Chennai.

There are also special events with all women crew or women drivers only. Lavasa rally is one of the most glamorous one with high profile celebrity attendance.

Passage Controls

Passage controls or check points are different than Time controls mentioned earlier. They are placed so as to ensure that the competitors are on the correct route. Passage controls are marked with standard symbols and are difficult to miss (unlike Time controls).

Each control is manned by marshals or volunteers. While marshals have prior rally experience, volunteers without the experience are trained for the rally. The training not only covers recording time, but also includes first aid assistance, wireless communications etc.

Here is a picture of a passage control:

Brilliant Thread Sudev! Rally driving is just as you said - for real men on real roads, and thats why it seems all the more alluring. The sad part - not much information for the average car enthusiast - now gets solved.

What do you think would be a good start for a newbie from Mumbai? Isnt Mahindra Adventure more about off-roading and need some experience with it (off roading)?

Mahindra does both. For off road - 4w vehicle guys - they do Challenges and for two wheel vehicle owners Adventures and Drives.

That would be one place to start with. Though Goa, Pune also have events.

The Marshals

Marshals are different breed of motoring enthusiasts altogether. They play an essential role in running of any rally (for that matter all motor sports) and perform vital function of timing at controls. They also ensure tracking and the safety of participants (even in a TSD Rally):

Marshalling is tough job but enjoyable as well. Marshals are up and travelling before the rally starts and go to sleep much after it's over. Check out some of the accounts written by marshals themselves:

The Mughal Rally - A Marshal's account

The Winning Strategy

Given that you have to come up with the least amount of penalties, the only guaranteed way of winning a TSD rally is to remain on time all throughout the course.

Many devices are available and are used by the Navigator to do constant calculations throughout the rally. He/she has to calculate their current location and the time at which they should have reached their current location. After this, he/she has to compare that with the ideal time of arrival. The difference in between these two is then used by the team to understand how fast or slow they should be going to maintain the ideal situation. This way, they do not get surprised at a time control since they would be always running on time.

However, to calculate correctly you also need to know the correct distance reading (odo). As mentioned earlier as well, many devices are available but the dictum in a rally is that the road book is always the Bible and cannot be wrong. So even if a GPS device is being used by the competitor, they still need to keep noting the error in the GPS reading with the road book and keep correcting themselves for this difference in the distance.

One of the easiest ways of noting and correcting the difference is to check the distance reading on your device from a constant point. Calculate the distance of your position from a constant (non-varying) point on your device and the same distance on the road book. The difference between these two would give you the error (between the device and road book). While choosing a constant point on the map, you have to be careful as well. Say for instance, a cross road in comparison to a curve on the road - there is no doubt that the cross road can be an exact point, but a curve can vary and you cannot have an exact reading of the distance. In addition, there are other indicators that can give you a very precise idea of distance reading for instance, a milestone or a building.

This constant calculation takes its toll on the navigator who also has to guide the driver onto the correct route. Thus, good teamwork between the driver and the navigator is extremely essential to keep a good progress. Of course, practice and persistent approach is basic to make winners.
