Why am I here ?

3. Introductions Who am I ? Why am I here ?
Every Runner believes they're a Course Measurer
Jones Counter is the only method recognised by AIMS/IAAF

4. Agenda - Theory Defining the Road Race Course Calibration Baseline
Bicycle Calibration
Measurement of the Course
Re-calibration
Course Calculations
Course Corrections
Reporting & Certifications

5. Agenda - Practical Fitting the Jones Counter
Measurement of a Calibration Baseline
Calibration of the Bicycle
Practical Course Measurement Exercise

6. Essential Tools of the Trade
Bicycle
Jones Counter
Steel Tape
Thermometer
Spring Balance
Calculator
Marking Materials
Notebook
Safety Equipment

7. Points to consider when setting out the Calibration Baseline
Straight
Traffic free
Able to be ridden in both directions
Good, consistent Road Surface
Close proximity to Start/Finish
Avoid sinks/storm drains / pot holes etc
Clear of any obstructions
Consider the optimum length available; (400m recommended but not always
possible)

8. Errors in Baseline Measurement
Temperature
Tension
Alignment
Non-standard/poor quality Tape
Miss –counting of the number of Bays
Inaccuracies in marking

9. Baseline Location

10. Baseline – Temperature Correction

11. Calibrated Measurement Device
Remember the device consists of the Bicycle,
the Jones Counter and you riding that Bicycle.
Also consider anything you might be carrying.

12. Calibration
Remember to apply the Short Course Prevention Factor of 1m per kilometre.
In the above example multiple 5,584 ; the counts ridden by and divide by 0.5 (the length of the Baseline in kilometres) to give a Working Constant of 11,179 counts per kilometre.

13. Calibration Calculations
Pre-Measurement or Working Constant
Post-Measurement or Finish Constant
Working Constant for the Day; the average of the Working & Finish constant
Note ; for your initial measurement and the setting out of the Kilometre marks you would use the Working Constant. However’ it is the Constant for the Day which should be used and therefore minor corrections will need to be applied.

14. Sample Calibration Data Sheet

15. Measuring the Shortest Possible Route (SPR)

16. Defining the Shortest Possible Route (SPR)

17. Different Routes around a left-hand Turn
Note that riding to the Right of the centre of the junction
you will typically measure 12m longer; hence the need to
define the course before you start your measurement.
