Since this thread is on the international section, I feel it is not out of place to mention my views, whereas I should be a bit more hesitant on intruding in US domestic aspects.
My qualification to comment is partly from the fact that I was one of the first certifiers to introduce a requirement to have a course checked after ten years after the original measurement. I think it was around 1997 that I introduced the practice in the South England. I would have liked to have specify 5 years as the limit, but it was clear we should use the longer time (10 years) as an initial step for fear of overloading our accredited measurers.
This has worked very well for the last ten years. Of course only a modest fraction of courses actually last ten years unchanged, so the load is not high. What is interesting is of those that are inspected then measured by a measurer under my ten year rule, a significant fraction of courses are found to have changed, either (A) before an actual remeasurement is has been made, or (B), rather rarely, when a check measurement is made on a course which to all appearances to a skilled measurer is unchanged.
The adjustments that have to be for (B) are usually quite small - the worst one I can recall recently is a 2mile 104 yard course which was remeasured(twice) at 2m 90y. There was absolutely nothing wrong with the paperwork on both measurements by different highly experienced UKA grade 1 measurers (equivalent to IAAF grade B standard) The race director swears that there have been no race boundary changes. We can't discover the reason for the change but we go forward with the latest measurement.
I find the the main problem we pick up by the ten year check is slack race directors, who make changes - start/finish/marshalling - but still say the course is unchanged. Very often this is associated with a change of race director. Let me quote a (typical) recent message from a measurer when attending a ten year old course that has been declared each year as unchanged and therefore issued with an annual renewal of the original certificate, until this year.
quote:
I rode the course with the race director using the start and finish that he advised me were those used last year. I found the (10k) course to be 106m short. He is new to the job of organising the race and he did think that whilst the finish has always been in the same place the start has varied for some reason.
This problem should never arise if each year the race director consults the original measurement report and lays out the course as measured. But they clearly dont....
The conclusion of this ramble is that I am ready to try and move the UK measurement procedures to a five year check by a qualified measurer. But, just as now with our ten year checks, I would say the following
quote:
For 2007, I will not renew Certificates of Course Accuracy originally issued before 1 Jan 2002, unless an accredited course measurer with current knowledge of the race is prepared to vouch that remeasurement is unnecessary. This will involve him checking that the present race director still has a copy of the original measurement report, and possibly visiting the course with the race director to confirm that no changes have taken place. In this case the measurer's out-of-pocket expenses must be reimbursed by the race director according to the normal arrangements. I will then issue a new certificate based on the original measurement and the measurer's inspection.
In the event that the measurer is not satisfied he should recommend that a remeasurement be carried out.
My view is that the AIMS/IAAF 5 year remeasurement rule does not target the problem with lax race directors as precisely as my inspection rule, and I argue that my proposed slightly lower standard of check after five years will save some unnecessary measuring when it is clear to a qualified measurer that all is OK.
Of course things may be a bit different in those countries such as the USA which allow unqualified people to measure, so we are unlikely to achieve a fully worldwide standard.
