GSSC Summer Fling Rally

TSD Rally. Registration 10:00 - 10:40. Mandatory Driver's Meeting 10:45. Calls roll off at 11:00 AM. $10 per team (driver/co-driver) for GSSC members, $15 for guests. Will meet for lunch and awards ceremony at rally end. Start location in Vinings, see below for location. You will be given the time on this rally.


General Instructions:


The object of the rally is to drive the prescribed course at the prescribed speed. A perfect score is a 0. Points are awarded on the difference between the calculated time and your actual time. 1 point = 1/100th of a minute. Scores are capped at 300 points per stage. The team with lowest combined score is the winner.


Check points are indicated by the designated orange check point sign on display at the rally start. After reaching a check point, do not pull off but continue on the rally course.


The following items or actions are forbidden once the rally starts and will result in immediate disqualification: Cell phone use, using a GPS or navigation type system, failure to obey traffic laws or speed limits, driving while intoxicated.


Only through public roads are used in this rally. Driveways, parking lots, private roads and roads with gates across them do not exist and should be avoided. Other non-existent roads are illegal entries and roads marked "NO OUTLET", "DEAD END", "ROAD CLOSED", "NO THRU STREET", etc. Roads which clearly end in a garage, plant, plant entrance or similar areas also do not exist. The only exception to this rule will be the parking lots at the start and finish, the end of odometer calibration leg, and breaks. Anything that does not exist cannot be considered for any purpose. The following variations in road designations are immaterial: (1) Spacing of words in a name; (2) Unless otherwise specified, designation of a route name or number as US, County, State, Interstate, East, Alternate, etc. In addition, every attempt has been made to proof read the driving instructions. There are no attempts to fool or trap the participants into going in an incorrect direction. Spelling errors are unintentional.


Participants must have a current driver's license and must sign the Waiver Form. Vehicles must be registered, insured, and pass a basic safety inspection.


Route Instructions - The numbered instructions are to be done once only, in numerical order; never skip an instruction; never do a numbered instruction more than once. Complete each numbered instruction before you start the next one. During the Odometer Calibration Run (see below), mileages are given. The principal road will always be obvious, and should cause no confusion. If you are to leave the principal road, or if there might be any doubt about which way you are to go, you will be given a route-following action . At some intersections this principal road may be determined by pavement surface continuity, a curve warning sign, the center line on the pavement, the placement of a stop sign or a yield sign, the continuation of multiple lanes in your direction of travel (such as when you are upon a limited access highway), straight as possible, etc.


Odometer Calibration Run – The first stage of the course is a non-timed event with mileage given in order for competitors to compare their own odometer to the one used to measure the course in order to calculate an adjustment factor. For instance, if the official mileage for the OCR is 10 miles but your odometer indicates that you have only driven 9.7, you can calculate an adjustment factory by dividing 10 by 9.7 (10/9.7 = 1.03). This indicates that if you the CAST were 100 mph you would need to drive at 103 mph to keep on time.


Some definitions you'll need to know:


  1. CAST – Change Average Speed To. This is the speed you will attempt to keep over this section of the course until such a time as you are directed to change to another speed. You may have to speed up or slow down to keep to this average speed based on things like stop signs, sharp curves in the road, a man burning his yard while standing in the road, etc.

  2. Pause – Every now and then we run into a traffic light we couldn't avoid. At long lights, we add time (the pause) to make up for the period spent waiting on the light. If you are lucky and drive right through the light, you will still need to add this pause to your drive to be on time. There are no check points immediately after an indicated pause.

  3. Free Zone – A section of the course during which there will be no timing controls (check points). Usually indicative of heavy traffic or other factors that would make it difficult to stay on time in this area.

  4. NRI – Numbered Route Instructions

    Hey Scott/Kyle,
    That would be my first time attending this event so can you tell me more about it ?
    Do we get to drive our own cars as fast as we feel like on a reserved road or something of that type ?
