The terminology "block to block" refers to the chocks/blocks that keep the wheels still. Nothing to do with block time. Just to clarify! Sometimes referred to as "brakes off brakes on".And just to be pedantic it shouldn't take much more than 30 mins Cumbernauld to Fife, total 1hour at 85knots. Though if, like me, you go off course for a jolly on the way it could take all day!!!
