Tempo run course measured!

This morning I got out and wheel measured my 2 mile tempo run course. You can also do this with a bike computer. I took a can of spray paint and put markings on the sidewalk every 400 meters. This time I put a big 4,8,12 and mile marks, for 400, 800 and 1200 meters. This way I can track my speed or splits during the run. It turns out the old course was 1.95 miles or about 10-15 seconds off. This morning I ran 13:45. The old course record was 12:20:01, worth about 12:30-35 on the new one. Now that cooler weather is here I can add this to my weeks workout list. It helps to have a neighborhood course marked off. Car odometers are terribly inaccurate if you decide to mark your course that way. A surveyor's wheel is the way to go. Accurate. Yout just have to account for tangents. Mark each curve and corner the same way. Now, go mark your own favorite course.
