I copied this from a sports bicycle site and it outlines a route from the Green Line as far as Tapuach Junction and Rechalim:
It may be confusing as the route is a bit circular. It starts at Rosh HaAyin and ends at Givat HaKoach, passing through Bruchin, Ariel, Rechalim, Peduel, etc.
A bit more detail
A bit more
But you notice the up and downs and most importantly, the 125 meter high advantage of the area of Ariel over the rest of Israel.
