good road is the Marlborough to Pewsey road, not sure of its name, also the s-bends outside of Burbage towards Tidworth. A good ride is from swindon, out to Marlborough, on to Pewsey, then out towards Upavon, then either loop round back to Tidworth, or out to Amesbury. You could even just go from Pewsey, out towards Devizes, then out towards Lyneham, or back via Marlborough. Just be careful as the roads can get quite crudded up with dirt from farmers fields,
