Reply to "Measuring Track portion of a 5km Course"

I just tried this on a 400 meter track which I measured earlier this year with a calibrated measuring wheel.

Using Google Earth I got 399.42 meters. I used the length-width method, and the length at the inner line was 397.54 m. I added 1.85 m to account for the 30 cm offset.

Things got a tad blurry when trying to find the outer edge of the inner line.

Close but no cigar.

My measuring wheel measurement of the track may be seen by downloading OH10005PR from the USATF course search web site. All calculations are on the map. The track was measured because they had lost their original surveyor's certificate and had somebody who wanted to go for a Guinness record of 11 marathons in 11 days.
