Conveniently, looks like the Ace route without motorways is similar in length / time to the Runnymede group (according to Google maps). If anyone is meeting here, please let me know!! If not, I'll just go to Runnymede myself (or straight to Oxford, for that matter).
IF people are interested, this looks like a good potential route - no motorways:
Leave Ace at 9:30
A40, through Gerrards Cross
Beaconsfield
High Wycombe
West Wycombe
Stokenchurch
Postcombe
The A418, to rejoin the A40, and enter Oxford via Wheatley and Headington. Join Kosmic's group at the Peartree Interchange.
Pretty much following the A40 the whole way. I have no idea if that route is any good, it seems like there are some nice bits on it (and it's better than the M40!)
Please post up any comments AND WHETHER YOU WANT TO TAKE THIS ROUTE!!
See ya out there...
