Course Measurement Training Seminar 24 October 2015

Introductions Who am I ? Why am I here ?

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

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

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

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

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)

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

Baseline Location

Baseline – Temperature Correction

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.

Calibration Remember to apply the Short Course Prevention Factor of 1m per kilometre. In the above example multiple 5,584 ; the counts ridden by 1.001 and divide by 0.5 (the length of the Baseline in kilometres) to give a Working Constant of 11,179 counts per kilometre.

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.

Measuring the Shortest Possible Route (SPR)

Defining the Shortest Possible Route (SPR)

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.
