What is a rally? “A sustained flurry of blows in a boxing match.” (1825) “A quick recovery from a state of exhaustion, a renewal of energy.” (1826) “A competitive event for motor vehicles, usually over a long distance on public roads.” (1932) - Oxford English Dictionary, 2nd edition
Tip #1: Read the instructions Read ALL the instructions! • General Instructions • Read for definitions (MP = Milepost) • Supplemental Instructions • Rules from the rallymaster specific to this event • Route Instructions
Sections and Zones • Sections • TRN (Transit): No CAST; if you drive exactly at the posted speed limit you will get through it perfectly on time. • TSD (Time-Speed-Distance): CAST is given; goal is to be on time all the time; you may be timed anywhere in the section; checkpoints are closed (do not stop!). • RTZ (Rally Transit Zone): No CAST; you may be early or late within the section; there may be a checkpoint at the end of the section; scoring is within 1 minute. • Zones • Free Zone: area without checkpoints • This might be a good place to mention…don’t stop at the checkpoints!
Reading Route Instructions • Start time is the time of day • Add your car number to times in instructions, OR • Set your clock behind your car number in minutes (e.g., if you are car 15, set your clock back 15 minutes so that at your out time,11:15, your clock reads 11:00) • Mileage: the mileage IS the instruction • Alpine: start at the dot, exit at the arrow • Things in parenthesis are your friends! Instructions in parenthesis are (intended to be) helpful comments. They are not part of the instruction. They are not trying to trap you.
Pauses & Time Decs • Pause • The best place to take a pause is not necessarily at the mileage where it’s indicated. Read ahead! • Time declarations • Don’t hurt yourself, don’t hurt others, time decs are your friends • Declarations must be made for some number minutes + 30 seconds to place you “between” cars. • Tip: slow down by ½ or ¼ CAST & start the stopwatch. Your delay is ½ or ¼ the time shown on the stopwatch. (e.g., CAST is 40; if you drive at 30 for 60 seconds, you will be 15 seconds late.)
Basic Calculation Time = (distance * 60) / speed • Mileage = 1.0; CAST = 40 • Time = (1 * 60) / 40 • Time = 1.5 minutesThe end of an RTZ might be a good place to practice calculation!
