Time-Speed-Distance (TSD) road rallying can feel overwhelming for beginners. Trying to navigate, maintain a precise average speed, and hit secret checkpoints down to the second on your first weekend is a recipe for a headache.
The secret to success is to build your timing skills gradually. Instead of trying to master everything at once, use this step-by-step progression to transition smoothly from a complete novice to a seasoned pro:
- Stage 1: The Survivalist – Ignore the clock entirely. Focus 100% on reading the route instructions so you don’t get lost. After all, you can’t score well at a checkpoint you never find.
- Stage 2: Seat of the Pants (SOP) – Start tracking your speed. The driver relies on intuition to hold the target average speeds, learning to drive slightly faster when moving to compensate for intersections and slow corners.
- Stage 3: The Intermediate Calculator – The navigator introduces basic math (Time = Distance / Speed) to calculate ideal times at each Change Average Speed (CAS) instruction. This is where you learn how open versus closed checkpoints—and different scoring styles like Evansville and Madison—change your baseline numbers. You will also learn to calculate an Odometer Correction Factor to account for any discrepancies between your car and the rallymaster’s odometer.
- Stage 4: The Advanced Calculator – Increase your precision by calculating target arrival times for every route instruction. This allows the team to make frequent, micro-adjustments to their speed rather than large, panicked corrections.
- Stage 5: The Human Computer – Take timing to the micro-level by calculating target times at regular, fixed distance intervals (like every 1 km or 200 meters).
- Stage 6: The High-Tech Team – Outsource the heavy lifting to predictive electronics (such as an ALPHA-PRO) or smartphone apps (such as Richta or Rabbit Rally). The technology gives you real-time feedback on whether you are early or late, shifting the navigator’s job from mental math to flawless data entry.
⚠️ The Golden Rule: Safety always comes before the scorecard. No matter what stage your team is in, if you get delayed by a wrong turn or traffic, never speed recklessly to catch up. Use a Time Allowance to legally and safely request a penalty-free delay at the next checkpoint.
