I was encouraged by one race organizer to supply waypoint information about the timing points, and so I have done that for some courses-- marking points using a gps device and then creating a .kmz file that shows up in Google Earth, and also constructing a chart showing latitude and longitude for each point.
Apparently it was a big help for the folks who put the mile signs out at the Marine Corps Marathon, and for others who have gone to look for the points. But I need a little instruction on how best to (1) construct the chart, and (2) advise someone how to use it.
Specifically, is there a way to get around reading and typing all of the numbers to create the lat-long chart, and on the other end is there a way around typing in all those numbers in order to find the spots?
