Welcome primalgeek! Lots of new people this time , great!
hmmm - not sure about the best route, depends how much you like hills! I am sure some of the locals will be along shortly with expert advice.
If you are worried about this being your longest day yet, you could always cycle to Linlithgow and take the train to Falkirk, and then decide after the CC Ecosse ride whether you want to cycle all the way home or catch the train again. A cheap day return is only a few pennies more expensive than a single ticket.
Something like this - many variations possible, depending on the weather & what we fancy. Longniddry - Gifford cafe - Longniddry are the only fixed points along the route.
What's up Jim? Hope all is well in Weegieland

Yes and no, just some local difficulties to overcome.
