Saturday, June 6 there are two bike events in the DC area.
Cyclefest at Lake Fairfax. Sponsored by The Bike Lane to raise money for trail improvement. They have organized rides, seminars, classes, stuff for sale.
sounds like fun, but ....
The Wilson Bridge Bike and Pedestrian path opens at 1pm. It'll be great to have a southern crossing of the Potomac.
WABA is leading convoys to the bridge from various locations, but I'm planning to do my own modified version of the Greater Washington Loop. Starting somewhere in Arlington and going counter-clockwise through Georgetown, Bethesda, Silver Spring, Mt Rainier, NE DC, Capitol Hill, SE DC and getting to Oxon Hill around 2pm. I haven't mapped the distance yet, but it looks to be around 50 miles on the route I plan.
