One of the sweetest Audax's out there is the 200 From Droitwich to Towcester.
The start is at a pub in Droitwich, controls are at a bakers shop in Shipston-on-Stour, a garden centre in Towcester and a Shell filling station in Wellesbourne.
No INFOs.
Not much chance of a shorter route and plenty of food en-route.
