There is a somewhat competitive race in rockville on sunday, The Home Run 5k/10k. Both races have prize money and are competitive up front. The start is next to my place in the panera parking lot at Federal Plaza. Both courses are rolly out and back courses. Some expressed interest so I wanted to get this out.
