Just a 10-minute drive from the M4 and Swindon, the Aldbourne circular route tours the North Wessex downs (Area of Outstanding Natural Beauty) and The Ridgeway on rolling hills in untouched countryside. Being so quiet but easily accessible, it makes a great place to zone out from day-to-day life. Doctor Who scenes have been shot in this village. The route begins in the village of Aldbourne which has spaces to park your car and two pubs for post run refreshments!
