I've been plotting the Twilight 600 in Google Maps, and it's coming out under-distance.
Here's what I've plotted:
https://goo.gl/maps/VBXC1RksJe12In summary ( Controls as I understand them in
BOLD ):
South Queensferry, Crieff,
Aberfeldy, Crianlarich,, Glencoe,
Corran Ferry,Acharacle, Glenuig,
Lochailort, Gelnfinnan,
Fort William,, Ballachulish
Oban, Tyndrum, Crianlarich,
Lochearnhead,Callander,, Br of Allan, Fallin, Grangemouth,
South QueensferryIt comes out at 589k, which is quite a bit under-distance.
Am I going the Wrong Way somewhere, or is the route historically under-distance?
I can always push the start / finish controll back to Edinburgh to make up the shortfall, if necessary.
EDIT:
Looks like there's a control at Kelty.
That seems to pretty much nail it down.
