Bicycling (Commute) 6:17  1.41 mi (4:27 / mi) +10m 4:22 / mi
From the Bethesda Metro Station to Northfield Rd. I went back on a slightly different route along the backside of Bethesda Elementary School. It seemed less hilly even though there's a potential for more traffic. My left knee has been causing discomfort at times when I walk, and am on stairs.
