What's a "
Touring GPS"? Sounds like something you'd use for navigation.
There are quite a number of GPS units that will record your position/track/ride.
Some of the cheaper ones will let you load a route and follow the line on the screen and provide basic turn notifications.

You probably want to indicate how long you are riding for.
