From Northfield Rd. to Old Georgetown Rd. via Greenwich Park, to W. Cedar Ln. to Rockville Pike, to the Bethesda Trolley Trail to Maple Ave. to Old Georgetown Rd. to Huntington Pkwy. to Custer Rd. to Northfield Rd. I probably shouldn't have run this distance before racing with heavy competition in the M45+ category at the Flying Pig but it was a nice enough day. I saw Pat Zerfas along the way and stopped to talk as she was headed out on her run.
