In the last year, I have been asked on four separate occasions whether I can modify an existing, active certified course and re-certify it. My simple answer: "Yes. By starting all over from scratch. If we change the course, USATF considers this a new course". Whether common sense and USATF allow adding a few yards to the finish and subtracting that same amount from the start, for instance, as I have been requested to do, I just don't do it. I sense that there are some permissible exceptions.
