"Getting to the bridge didn't take that much longer than simply getting home, home in my case being Dunfermline and the bridge being the Clackmannanshire bridge (the newer/nicer one of the two there).
From there it's just a few minutes to the quiet, utterly flat and straight cyclepath that starts near Alloa and goes all the way back to Dunfermline. Nice leisurely pedalling as a "warm-down", so to speak."
@userfriendly, do you take the route through Clakmannan shown on OSM or is there a better option?
I'm heading from Dunfermline to Falkirk tonight for dinner and fancy trying something different to my normal route of Crossford, Cairnyhill, Culross and Kincardine (the forks).
