  1. Select a safe course and measure it as accurately as you can. (Use an OS 1:25000 map, a bike, a GPS, or, worst, a car)
  2. Prepare a course map
  3. Notify the police and follow any safety recommendations
  4. Only after 1, 2 &3 are you ready to contact an accredited measurer and make an appointment for an accurate measurement. The measurer will make a charge (see guidelines) and you should ask for an estimate.
  5. Supply the measurer with the following:
  6. On the agreed day meet the measurer and show him the course. It is usually best to accompany him on a bike. But a car may also be suitable. On busy roads the measurer may need someone behind him to 'protect' him from the traffic as he concentrates on an accurate measurement. Busy courses may need to be measured at a quiet time, e.g. early on Sunday morning. You may find it worthwhile to consult the Safety Code for Course Measurement so that you have an appreciation of the procedures the course measurer uses to make the measurement safe. The course measurer will seek your help to ensure his safety while riding, and he might not be able to complete the measurement at a single visit if he discovers hazrds which he has not planned for.
  7. After the measurement the measurer writes a report and sends copies to the race organiser and to the area measurement secretary, who issues the Certificate of Course Accuracy. Without a valid certificate or a renewal for subsequent races, any permit issued for a race advertising a specific distance would be invalid.
