There's a convergence of two great cycling paths at the Herndon, VA Residence Inn. One's a fantastic wooded but small asphalt mountain bike path that's a ten miler round trip with a few water hazards! I've seen plenty of deer and coyotes and other critters and a lot of really nice houses. The other's a paved long path that goes 25 miles or more east to Alexandria/DC or 10 or more miles past Leesburg. I think there's a connecter path that goes north to Maryland, also.
