Ride With GPS free edition is what I mostly use for route creation, and the bike club I'm in (Potomac Pedalers) has a paid subscription. Almost all club rides post RideWithGPS files on the club web site.
I also use Strava to track my overall biking (and hiking) mileage. I'd been using the free version but was given a full paid "Summit" version as a birthday present, and you can create routes and downloadable files there, too. I think it is easier in RideWithGPS, but Strava does have one cool feature: you can create a route and then turn on a switch that maximizes segments that are favored by Strava users. That means that you are more likely to end up on better bicycling roads, but in my experience it usually means a longer route - there is a trade-off.
