Depending on the experience/fitness of who turns up on Saturday, I would suggest we go Inverkeithing - Crossgates - Hill of Beath - Kelty - Blairadam ... then HLaB's route round Loch Leven - Cleish Hill - and follow the reverse Edinburgh/St Andrew's route through Crossford - Rosyth - Inverkeithing.
Alternative would be to go to Crossgates - Cowdenbeath - Lumphillans - Lochgelly - Balingry - Scotlandwell etc.
Plenty cafes, all tried by various folk, so we could do a stop-at-every-cafe-ride and have a real caffeine fix

For those coming from further afield by train/bike, Inverkeithing is about 40mins ride from Linlithgow and 60-70 mins from central Edinburgh.
