From Rosedale Ave., Bethesda, MD, to 12th St. SW, Washington, D.C. I wonder if this is the last time riding to work from Rosedale Ave. I felt headwinds starting out. It turned out that they were coming from the NW but I didn't know it until much later. After Massachusetts Ave., I caught a guy and then he accelerated to faster than I planned to go so I drafted on him several miles till just past Fletcher's Boathouse. I took over from there into Georgetown. We were doing 23-25mph on the downgrade and 22mph on the flats. Finishing up I was trying to keep the average pace above 18mph but with traffic, that didn't work out. I did a good amount of boxing-up our stuff on Sunday.
