Hi there, geekgirl. The W&OD is just plain crowded on weekends, but I would definitely recommend that you head west towards Leesburg. Once you get past that town, the strollers and roller bladers thin out a tiny bit. And the scenery is much more pleasant in that direction as well (borderline rural).
I have no idea where you could rent a bike, but here are a couple of shops you could call:
- Spokes in Ashburn is close to Landsdowne.
- Plum Grove Cyclery is farther away in Leesburg, but it's a great shop on the edge of the historic district.
