Calibration Courses

chrismontgomeryMember

Hi all. I am relatively new to measuring courses compared to most here, but have been "unofficially measuring" small local races for a couple years where I live, using the USATF standards.

I have what might seem an obvious question to some, but would like to get input on it. I have used a 1000 meter course before, and the math on that was easy as it relates to the counts per kilometer when actually measuring the course.

What if you use a 300 meter course? If I do my calibrations and at the end of all of the procedures I come out with a working constant of say 2800 counts for 300 meters, how does that get turned into what the count should be for a kilometer. Is it simply 300 meters is 2800 counts, 100 meters is 933.333333 counts, and therefore 933.33333 x 10 = 9333.3333.

Therefore 9333.33333 counts = 1000 meters?

Again this might be obvious, but just want to make sure I'm going about this the right way.

Thanks in advance,
Chris

Chris,

You've got it right except, for course layout, you should multiply the 9333.33333 by 1.001, the SCPF (short course prevention factor), and wind up with a constant of 9342.67 counts per kilometer.
