You're less than four miles from Union Station at Mile 0 in G-town. You could either ride on Capital Crescent Trail until that ends and then the streets (lots of safe cycling infrastructure, bike paths, etc.) or head to Foggy Bottom Metro station (still need to ride to get there) which I think you can take your bike on any time except weekday rush hours. Get on either of the Blue, Silver, or Orange lines and head east and transfer at Metro Center and get on the Red line which goes to Union Station. I'd actually just ride the whole way, it's a nice pleasant ride if you take the bike safe routes.
