This is a good mix of straights, bends, scenery, and what great biking is about. Its not a race track, but allows a brisk pace for several hours. There are some Guardia Traficos around and you will have to share the route with a moderate amount of other vehicles, although there are plenty of overtaking opportunities.
Technically the N320 starts/ends at La Gineta, rather than Albacete, where you will find a great buffet restaurant at the intersection with the A31.
Should your route then take you South West, there is a 13 mile dead straight road from La Gineta to Barrax, with open fields either side, allowing you to simply hold it against the stop for as long as you dare - too rural for the police to even bother with.
