Bicycling (Commute) 42:10  11.9 mi (3:33 / mi)
From 13th & C St. SW, Washington, D.C., to Northfield Rd., Bethesda, MD. I started at 5:57pm. My legs were sore from the morning and the rides the previous day. After rounding the Jefferson Memorial, with headwinds getting to Georgetown, I was slow. After reaching the other side and another mile later, a rider passed me so I drafted. He was shorter and seemed to me to be older. However, he was moving really well, even as we turned uphill. He blocked enough air for me to keep up at a comfortable pace, with me having to push only now and then as we passed others or hit a bridge overpass. He turned away at Dorset Ave. so after that I moved slower again, even though I was putting in a little more effort. We had been moving up the hill rather well together so I must have been moving rather a lot more slowly early on.
