Typical route from work -- through Bolling AFB and into the city, up to Georgetown, across the Key Bridge and then instead of staying on the Mt Vernon trail after Memorial Bridge, cut over to Boundary Drive, work around the Pentagon and then ride bike lanes through Crystal City. There are some sketchy spots but it's soooo much better than the narrow, crowded MV Trail. Zip along southbound on the wide, newer trail along Potomac, then regular bike routes through Alexandria. There is one very weird turn at Mile 23.7 that looks NOTHING like it does on the map. Rested a bit under the big bridge before crossing and tackling the Col du Casino and the descent on the other, steeper side down the Col du Oxon Hill. Temps hovering around 90, humid, but ... warm weather is best! Contact points objected some after about 25 miles and a rest shut them up for a bit. They were glad, however, to complete the mission. Legs felt pretty good. Still got a ways to go though.
