This is the story, all about how, this race got started in my town.  I don't have time to write an entire song parody for an example race, so time for a cut and paste from the Scott Coffee Run page:

The Scott Coffee Moorestown Rotary 8K is named for one of the founders of the race, Scott Coffee, who passed away in the summer of 2006. Proceeds benefit the activities of Moorestown Rotary Charities and the Scott Coffee Education Endowment for scholarships. The race is presented by the Moorestown Rotary Club in cooperation with the Township of Moorestown, and the Moorestown Community House. 8K – flat and fast – starting and finishing at the Community House on Main Street. The traffic-free USATF certified course passes through the historic, tree-lined streets of 300 year old Moorestown. There are splits every mile and two water stops.
