In the current Runners World, July, there is an article "Fund-Raising 101" (page 108) that lays out the basics for putting on a 5 km run for your favorite charity. Point No. 4 is called "Choose a Course" and they urge you to stage the 5 km on a course that has been measured and certified by USATF. They cite a race director from Delaware, a Wayne Kurch <races2run.com>who says it can cost you up to $275 to have your course measured and about $125 extra to have it certified. What have I been missing all these years!
