Route creation and utilizing said routes is a standard feature of the Strava app/website. It doesn't require a premium subscription.
FYI Strava (premium or not) doesn't support importing routes. You have to build them on their website using their route builder.
EDIT: I just checked and apparently the ability to upload a GPX file and have it turned into a route is supported by Strava at the Beta "Labs" level. Here:

EDIT2: Tried it, it works!
