"I think the ads are boring," Jones said . "
"But it's cool for us.
"The American track and field listed 27 surveyors in New York, but Katz turned to Jones, who lives in London, to work with him to calibrate the Olympic trial course.

"Jones is one of the best surveyors in the world," Katz said . " Katz has been measuring courses since 1976.
"It's interesting to measure with such an excellent surveyor.

The extra width provides different ups and downs and gives runners the chance to go straight on the curve.
A new set of certified measurements is therefore required.
Jones and Katz measured 400 on Tuesday.
Directly measure the instrument with a steel tape measure near the East 90 Street engineer's door. At 10 p. m.
, They ride back and forth along the same section, calibrating the measuring equipment on the bike, which calculates the rotation speed of the wheel.
By four riding distances, the distance between the expansion calculation and correction of the tape measure in 85-is averaged 36mm
The temperature during the day, they are able to calibrate the standard for the rest of the measurements at night.
In order to measure the "shortest path" authorized by I"A. A. F.

Clain eventually manufactured and sold 2,300 of the equipment in nine years and then sold the business to the New York Road Runner club in 1982.
The profit helped 43-year-old Jones pay for his undergraduate education at Cornell University.

They went back to the New York Road Runner's office on the Upper East Side and sorted out their numbers.
AdvertisementKatz and Jones have "signatory status" so their measurements are automatically certified.
But because they were particularly serious, they invited an independent surveyor to accompany them last night because they marked the midpoint of each mile, every five kilometers and course.
Next week, Katz said he would submit a certificate of accuracy and a certificate of manual
A map of the course was drawn to American track and field officials.
Speaking of measuring the sealing surface for the glory of the movement, Katz said: "This is an art . ".
"It's a great feeling when these parts are assembled together.
