So I have recce'd the route, it's about 12 miles, nice and flat (as most S.Bucks routes are) and not too bad to navigate.
The pub (Royal Standard) has the following beers:
Knights of the Garter (YUM!)
Timmy Taylor's landlord
plus 4 others...
4 different kinds of cider
Multiple different belgian and french beers (including Abbeye)
AND 3/8 is a quiz night......
