Jamie, just a thought. BTCC is on at KH on Sunday. Kincardine bridge is closed so any traffic from the west that is heading in that direction will need to go via the roundabout at the services in Stirling then onwards from there, and that's where Dobbies garden centre is yes?
Could cause some problems possibly? Although you'd hope it would clear before half 10.
I'm waiting to hear from my cousin about helping him out with his Kart on Sunday, but if that's not on then I might well join you, but only for the run.
